What if the Massive Martian Lakes Weren’t Lakes At All?

Scientists from the University of Hong Kong (HKU) have presented new research that challenges the popular Gale crater hypothesis on Mars. Until now, data from the Curiosity rover indicated that this crater in ancient times could have been a deep lake. However, an alternative view of the same data showed that the crater may have never been a Martian lake.

Measurements of Asteroid Psyche Suggest It’s Likely Worth 10,000 Quadrillion Dollars

With the help of the ALMA telescope, scientists have carried out accurate temperature measurements on the surface of the asteroid Psyche. The object is known to be worth more than the entire global economy of our planet and will be the target of an upcoming NASA mission in 2022.

NASA Model On Star Resembling Our Sun

By the standards of the stars, the Sun is now “a moderately plump star in its prime.” But to thoroughly understand its evolution and try to predict future development, scientists need to find out what such bodies were like at earlier stages of development. Observations of young stars of the same type and, of course, modeling help a lot in this process.
