Planetary researchers announced a major discovery from the solar system's Red Planet on Monday – patches of water frost equating to "60 Olympic-size swimming pools" have been detected on Mars. The thin yet widespread layers of water frost were discovered atop three of Mars' Tharsis volcanoes, located on a plateau at the planet's equator, according to a new study published in the journal Nature Geoscience. The Tharsis volcanoes, a string of 12 large peaks, are the tallest volcanoes in our solar system, according to the study, which notes that the water frost was discovered on the volcanoes Olympus, Arsia Ascraeus Mons, and Ceraunius Tholus. The researchers calculate the frost constitutes at least 150,000 tons of water that swaps between the surface and atmosphere each day during the cold seasons," researchers from Brown University reported in a press release Monday, adding, "That's the equivalent of roughly 60 Olympic-size swimming pools." ...

Gliese 12 b represents one of the best targets to study whether Earth-size planets orbiting cool stars can retain their atmospheres, a crucial step to advance our understanding of habitability on planets across our galaxy," said Shishir Dholakia, who is a doctoral student at the Centre for Astrophysics at the University of Southern Queensland and lead author of the study. For the discovery, Gliese 12 b was first identified by NASA’s TESS (Transiting Exoplanet Survey Satellite) with follow-up observations performed by a combination of space- and ground-based observatories, including CHEOPS (CHaracterising ExOPlanets Satellite), MINERVA-Australis, SPECULOOS (Search for habitable Planets EClipsing ULtra-cOOl Stars), and Purple Mountain Observatory, and additional TESS observations. In the end, the researchers found Gliese 12 b had an orbital period of approximately 12.7 days, a radius almost exactly that of Earth, and a potential surface temperature of approximately 107°F (42°C)....

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 ...

This spiral galaxy is viewed nearly edge-on from our perspective, giving it the shape of a classic science fiction spaceship. This is why the astronomers at the Astronaut Memorial Planetarium and Observatory gave it this attention-grabbing nickname. The reddened light from the center of the galaxy appears yellowish due to thousands of light years of intervening gas and dust in the outer arms of this galaxy. The core can be glimpsed at through the last wall of dust in the center. NGC 2683 is a nearby galaxy. This image was taken as part of Advanced Observing Program (AOP) program at Kitt Peak Visitor Center during 2014.

The International Space Station (ISS) is a magnificent engineering marvel orbiting our planet, serving as a hub for scientific research and international cooperation. Many enthusiasts and stargazers enjoy observing the ISS as it passes overhead, creating a mesmerizing spectacle in the night sky. Tracking the ISS is an exciting and rewarding endeavor, and this article will guide you on how to do it effectively. 1. Know the Basics: Before you begin tracking the ISS, it's important to understand a few key details. The ISS orbits the Earth at an altitude of approximately 408 kilometers (253 miles) and travels at a speed of about 28,000 kilometers per hour (17,500 miles per hour). It completes an orbit around the Earth in roughly 90 minutes. 2. Find the Right Time: To increase your chances of spotting the ISS, you need to know when it will be visible from your location. Numerous websites and smartphone applications provide real-time tracking information tailored to your specific l...

In an age of scientific advancements and readily available information, it may seem perplexing that some individuals still believe in the concept of a flat Earth. However, the flat Earth theory is a hoax that lacks any substantial scientific evidence. In this article, we will delve into the reasons why the flat Earth theory is nothing more than a fallacy, debunking its claims and highlighting scientific evidence that supports the round Earth model. 1. Historical and Scientific Consensus For centuries, the overwhelming scientific consensus has supported the notion that the Earth is a spherical object. Ancient civilizations, such as the Greeks, Egyptians, and Chinese, recognized the Earth's round shape through observations of celestial bodies, ship disappearances over the horizon, and the circular shadow cast on the Moon during lunar eclipses. Moreover, modern scientific advancements have provided substantial evidence for a spherical Earth. Satellite imagery, space exploration...
