Astronomers Find a Multiplanet System Nearby

MIT astronomers have discovered a new multiplanet system that exists just 10 parsecs, or approximately 33 light-years, from Earth, making it one of the closest known multiplanet systems to our own. The star at the system's heart likely hosts at least two terrestrial, Earth-sized planets. Credit: MIT News, with TESS Satellite figure courtesy of...

Parker Solar Probe Captures Its First Images of Venus’ Surface in Visible Light

Credit: NASA's Goddard Space Flight CenterNASA's Parker Solar Probe has taken its first visible-light pictures of the surface of Venus from spaceSurrounded in thick clouds, Venus' surface is usually hidden from view. However, in two current flybys of the Earth, Parker used its Wide-Field Imager, or WISPR, to image the whole nightside in wavelengths...

NASA Telescope Idea Could Spot Vegetation on Distant Exoplanets

Credit: Slava TuryshevNASA states it could detect "surface features" and even "hints of habitability" on distant planets.NASA is financing research for a conceptual telescope called a "solar gravitational lens" (SGL) that can allow us to observe remote exoplanets at a fantastic resolution-- a futuristic endeavor that might assist discovery at last if we...

Mercury Earliest Atmosphere

Nasa/JHU/Carnegie CreditMercury is a really peculiar planet. The tiniest in the solar system and the one nearest to the sun, it rotates slowly in a 3:2 spin resonance and experiences hot temperatures of up to 430 degrees Celsius during the day and cold temperatures of -170 degrees Celsius at night.Its average density is...

Chemistry Lab on ExoMars Rover Will Search For Evidence of Life on Mars

An international group of scientists made a tiny chemistry lab for a rover that will drill below the Martian surface, searching for previous or existing life signs. For ExoMars Reconnaissance is a joint venture involving the European Space Agency and the Russian aerospace company Roscosmos. NASA made a significant contribution to MOMA, the laboratory...
