WASP-193 b has a density of approximately 0.059 grams per centimeter cubed (g/cm3), which is comparable to cotton candy. For context, Jupiter has a density of 1.33 g/cm3, Saturn has a density of 0.69 g/cm3, Uranus has a density of 1.27 g/cm3, and Neptune has a density of 1.64 g/cm3. Therefore, despite being larger than Jupiter, WASP-193b’s density is far less than the largest gas giant in our solar system. Using the transit method, astronomers detected WASP-193 b using the Wide Angle Search for Planets (WASP) project as they gathered data between 2006 and 2008 and once again between 2011 and 2012. Through this, the astronomers were able to ascertain WASP-193 b’s planetary characteristics, specifically its orbital period, size, and density, as the exoplanet passed in front of its parent star. WASP-193 b is the second least dense planet discovered to date, after Kepler-51 d, which is much smaller," said Dr. Khalid Barkaoui, who is a postdoctoral researcher at the University of ...

The observatory has a packed schedule of science programs looking at all kinds of cosmic phenomena, like planets, stars, galaxies, black holes, and more. Webb will revolutionize our understanding of the universe — but first, researchers need time to analyze data and make sure that they understand what they’re seeing.  Webb has already captured more images beyond the ones you saw on July 12, and the Cartwheel Galaxy is just one example. Hold onto your intergalactic hats — we’ll be rolling those out in the coming weeks at nasa.gov/webb and on the NASAWebb social media channels. Some of those images give a first look at Webb’s capabilities, but are not part of science programs. In the meantime, you can revisit the first images at nasa.gov/webbfirstimages. We also have this page where you can find the full array of images and data at full resolution. News releases on results will be coming, too, once they have been reviewed. You may have seen scientists on social med...

Just a week after its first images were shown to the world, the James Webb Space Telescope may have found a galaxy that existed 13.5 billion years ago, a scientist who analyzed the data said Wednesday, July 21. Known as GLASS-z13, the galaxy dates back to 300 million years after the Big Bang, about 100 million years earlier than anything previously identified, Rohan Naidu of the Harvard Center for Astrophysics told Agence France Presse (AFP). "We're potentially looking at the most distant starlight that anyone has ever seen," he said. The more distant objects are from us, the longer it takes for their light to reach us, and so to gaze back into the distant universe is to see into the deep past. Though GLASS-z13 existed in the earliest era of the universe, its exact age remains unknown as it could have formed anytime within the first 300 million years. GLASS-z13 was spotted in so-called "early release" data from the orbiting observatory's main i...

Webb's First Deep Field is not only the first full-colour image from the James Webb Space Telescope, it’s the deepest and sharpest infrared image of the distant universe, so far. This image covers a patch of sky approximately the size of a grain of sand held at arm’s length. It’s just a tiny sliver of the vast Universe," said NASA Administrator Bill Nelson. “This mission was made possible by human ingenuity – the incredible NASA Webb team and our international partners at the European Space Agency and the Canadian Space Agency. Webb is just the start of what we can accomplish in the future when we work together for the benefit of humanity." “What an incredible honour for ESA and its international partners to reveal Webb’s first image from the White House,” says ESA Director General Josef Aschbacher. “Only with teamwork, dedication, and the human drive to push boundaries and explore have we arrived at this historical moment of seeing the deepest view of the ear...

The black hole is named Sagittarius A* (pronounced “A-star”), and the reveal of its image received an international rollout this morning in simultaneous press conferences held by the National Science Foundation (NSF) at the National Press Club in Washington, D.C., and the European Southern Observatory headquarters in Garching, Germany. The image represents 3.5 million gigabytes of data taken at millimeter wavelengths by eight radio telescopes around the world. “It took several years to refine our image and confirm what we had,” said Feryal Özel, an astronomer at the University of Arizona in Tucson, at the NSF press conference. “But we prevailed.” The data that went into making the M87* and Sgr A* images were taken back in April 2017 during the EHT’s inaugural observing campaign. Despite its distance, M87’s central black hole appears roughly the same size on the sky as that of our own galaxy’s. Though M87* is about 2,000 times more distant, it is also about 1,500 times large...

Solar Orbiter  closest approach to the Sun, known as perihelion, took place on 26 March. The spacecraft was inside the orbit of Mercury, at about one-third the distance from the Sun to the Earth, and its heatshield was reaching around 500°C. But it dissipated that heat with its innovative technology to keep the spacecraft safe and functioning. Solar Orbiter carries ten science instruments – nine are led by ESA Member States and one by NASA – all working together in close collaboration to provide unprecedented insight into how our local star ‘works’. Some are remote-sensing instruments that look at the Sun, while others are in-situ instruments that monitor the conditions around the spacecraft, enabling scientists to ‘join the dots’ from what they see happening at the Sun, to what Solar Orbiter ‘feels’ at its location in the solar wind millions of kilometres away. When it comes to perihelion, clearly the closer the spacecraft gets to the Sun, the finer the details the re...

On Wednesday, April 10th 2019,  the world was treated to something unprecedented - the first-ever image of a black hole! Specifically, the image captured the Supermassive Black Hole (SMBH) at the center of M87 (aka. Virgo A), a supergiant elliptical galaxy in the Virgo constellation. Already, this image is being compared to pictures like the "pale blue dot" taken by the Voyager 1 mission or the "Earthrise" image taken by Apollo 8. Like these images, the picture of the M87 black hole has captured the imagination of people all around the world. The Event Horizon Telescope (EHT) collaboration produced the first-ever image of a black hole, which lies at the center of the M87 galaxy 55 million light-years from Earth. The image showed a bright ring with a dark center, which is the black hole's shadow. In capturing this image, astronomers noticed a significant amount of polarized light around the black hole. Now, the collaboration has revealed a new look at...

Over the past decades, Jupiter has also been one of the favourite planets that astronomers and space scientists are looking to investigate. The reasons for interest in Jupiter by astronomers and space scientists are many. Not only Jupiter will answer many questions related to the origin of the solar system and emergence of life, but the presence of water bodies on Jupiter’s three moons (‘Ganymede’, ‘Europa’ and ‘Callisto’) has also caught the eye of various space agencies and has built the enthusiasm in them to explore the Jupiter. Being one of the largest planets in our solar system and mostly made up of Helium and Hydrogen, it is one of the brightest objects in the night sky after Moon and Venus. Jupiter Icy Moon Explorer”, abbreviated as “Juice” is the spacecraft in the development phase to explore the Icy moons of Jupiter, and Jupiter itself. The “European Space Agency” has given the contract to “Airbus Defence and Space” company for its design. The spacecraft will be a...

Following the completion of critical mirror alignment steps, NASA’s James Webb Space Telescope team expects that Webb’s optical performance will be able to meet or exceed the science goals the observatory was built to achieve. On March 11, the Webb team completed the stage of alignment known as “fine phasing.” At this key stage in the commissioning of Webb’s Optical Telescope Element, every optical parameter that has been checked and tested is performing at, or above, expectations. The team also found no critical issues and no measurable contamination or blockages to Webb’s optical path. The observatory is able to successfully gather light from distant objects and deliver it to its instruments without issue. Although there are months to go before Webb ultimately delivers its new view of the cosmos, achieving this milestone means the team is confident that Webb’s first-of-its-kind optical system is working as well as possible. “More than 20 years ago, the Webb team set out t...

In time for Valentine’s Day, NASA’s Imaging X-Ray Polarimetry Explorer which launched Dec. 9, 2021, has delivered its first imaging data since completing its month-long commissioning phase. All instruments are functioning well aboard the observatory, which is on a quest to study some of the most mysterious and extreme objects in the universe.   IXPE first focused its X-ray eyes on Cassiopeia A, an object consisting of the remains of a star that exploded in the 17th century. The shock waves from the explosion have swept up surrounding gas, heating it to high temperatures and accelerating cosmic ray particles to make a cloud that glows in X-ray light. Other telescopes have studied Cassiopeia A before, but IXPE will allow researchers to examine it in a new way. In the image above, the saturation of the magenta color corresponds to the intensity of X-ray light observed by IXPE. It overlays high energy X-ray data, shown in blue, from NASA’s Chandra X-Ray Observatory. Ch...

Webb fired its onboard thrusters for nearly five minutes (297 seconds) to complete the final postlaunch course correction to Webb’s trajectory. This mid-course correction burn inserted Webb toward its final orbit around the second Sun-Earth Lagrange point, or L2, nearly 1 million miles away from the Earth. The final mid-course burn added only about 3.6 miles per hour (1.6 meters per second) – a mere walking pace – to Webb’s speed, which was all that was needed to send it to its preferred “halo” orbit around the L2 point. “Webb, welcome home!” said NASA Administrator Bill Nelson. “Congratulations to the team for all of their hard work ensuring Webb’s safe arrival at L2 today. We’re one step closer to uncovering the mysteries of the universe. And I can’t wait to see Webb’s first new views of the universe this summer!” Webb has used as little propellant as possible for course corrections while it travels out to the realm of L2, to leave as much remaining propellant as possible...

Having spent just over a month in space, the Imaging X-ray Polarimetry Explorer (IXPE) is working and already zeroing in on some of the hottest, most energetic objects in the universe. A joint effort between NASA and the Italian Space Agency, IXPE is the first space observatory dedicated to studying the polarization of X-rays coming from objects like exploded stars and black holes. Polarization describes how the X-ray light is oriented as it travels through space. “The start of IXPE’s science observations marks a new chapter for X-ray astronomy,” said Martin Weisskopf, the mission’s principal investigator at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “One thing is certain: we can expect the unexpected.” IXPE launched Dec. 9 on a Falcon 9 rocket into orbit 370 miles (600 kilometers) above Earth’s equator. The observatory’s boom, which provides the distance needed to focus X-rays onto its detectors, was deployed successfully on Dec. 15. The IXPE team spent the next three...

The Space Launch System team is not just building one rocket but manufacturing several rockets for exploration missions and future SLS flights beyond the initial Artemis launch,” said John Honeycutt, SLS program manager at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “The Artemis I mission is the first in a series of increasingly complex missions that will extend our presence on the Moon. The SLS rocket’s unprecedented power and capabilities will send missions farther and faster throughout the solar system. With its two solid rocket boosters and four RS-25 engines, SLS produces more than 8.8 million pounds of thrust to launch each Artemis mission beyond Earth’s orbit and onward to the Moon. The rocket features some of the largest, most advanced, and most reliable hardware elements ever built for space exploration. To power the agency’s next-generation deep space missions, SLS delivers propulsion in phases. At liftoff, the core stage with its four RS-25 engine...

NASA Administrator Bill Nelson announced that Dr. Katherine Calvin will serve the agency in dual roles as chief scientist and senior climate advisor effective Monday. Calvin succeeds Jim Green, who retired from his role Jan. 1 as chief scientist after more than 40 years of service at NASA, and Gavin Schmidt, who has served as senior climate advisor in an acting capacity since the position was created in February 2021. NASA established the senior climate advisor position to ensure effective fulfillment of the Biden-Harris Administration’s climate science objectives for the agency. Schmidt will maintain his role as director of NASA’s Goddard Institute for Space Studies in New York. “I’m thrilled to welcome Kate to the NASA family, where she will bring her expertise in integrated human-Earth system modeling to help ensure the Biden Administration has the data needed to achieve the critical goal of protecting our planet.” Nelson said. “I also want to thank Jim and Gavin for their invaluabl...

The $10 billion NASA observatory unfolded the second "wing" of its massive primary mirror today (Jan. 8), bringing the light-collecting structure up to its full size and marking the end of the mission's long, risky and ultra-complex deployment phase.  As the final mirror segment folded in place just before 10:30 a.m. EST (1530 GMT). Just under three hours later, at 1:17 p.m. EST (1817 GMT), the mirror was locked into place as cheers and high-fives erupted at its mission control center in Baltimore, Maryland. After Webb launched into space on Dec. 25, the normally clean-shaven Zurbuchen pledged not to shave until its hair-raising deployment was complete.  "I fully expect to shave today," Zurbuchen said.  The mission team, for their part, seemed to ease the tension of today's final deployment by piping in music to their mission operations center in the Space Telescope Science Institute in Baltimore, Maryland. Among their music sel...

Today, Webb teams successfully deployed the observatory’s secondary mirror support structure. When light from the distant universe hits Webb’s iconic 18 gold primary mirrors, it will reflect off and hit the smaller, 2.4-foot (.74-meter) secondary mirror, which will direct the light into its instruments. The secondary mirror is supported by three lightweight deployable struts that are each almost 25 feet long and are designed to withstand the space environment. Specialized heating systems were used to warm up the joints and motors needed for seamless operation. “Another banner day for JWST,” said Bill Ochs, Webb project manager at NASA’s Goddard Space Flight Center, as he congratulated the secondary mirror deployment team at the Mission Operations Center in Baltimore. “This is unbelievable…We’re about 600,000 miles from Earth, and we actually have a telescope.” The deployment process began at approximately 9:52 a.m. EST, and the secondary mirror finished moving into its extended positio...

On Monday (Jan. 3), James Webb Space Telescope controllers began tightening the tension on its massive sunshield, a five-layer shield the size of a tennis court designed to keep the $10 billion observatory cool enough for science.  The task is the final step in unfolding Webb's sunshield, and should take up to three days to complete. With Webb being so new to space — the $10 billion observatory only launched on Dec. 25 — the tensioning was delayed by two days as engineers took a break for the New Year's Day holiday on Saturday (Jan. 1) and worked through couple of minor issues on Sunday. Engineers are now tensioning the first layer of the sunshield, which will continue through Monday if that goes to plan. Once complete, the Webb team will assess the deployment success and adapt the following four layers as required. The schedule calls for the deployment to finish on Wednesday (Jan. 5), but the timing of layer tensioning (and even...
