MIT researchers have discovered four new exoplanets orbiting a sun-like star just over 200 light-years from Earth. Because of the diversity of these planets and brightness of their star, this system could be an ideal target for atmospheric characterization with NASA's upcoming James Webb Space Telescope. Tansu Daylan, a postdoc at the MIT Kavli Institute for Astrophysics and Space Research, led the study published in The Astronomical Journal on Jan. 25.
With further study, says Daylan, this bright star and its many planets could be critical to understanding how planets take shape and evolve. "When it comes to characterizing planetary atmospheres around sun-like stars, this is likely one of the best targets we will ever get," he says of the results he presented earlier in the month at the 237th meeting of the American Astronomical Society.

The image comes from the Colour and Stereo Surface Imaging System (CaSSIS) camera. It managed to snap a particularly scenic spot for the visual milestone.
The snapshot comes from Dec. 13, 2020, and shows part of a "wrinkle ridge system" on a volcanic plateau. It gives scientists a peek at the history of Martian geology in the region.
Angara's launch confirms possibility of orbiting 23-tonne payloads — top brass - Science &
MOSCOW, January 29. /TASS/. The recent launch of the heavy space rocket Angara-A5 from the Plesetsk cosmodrome has confirmed the possibility of putting payloads of up to 23 tonnes into low orbits, Russia’s Deputy Defense Minister Alexei Krivoruchko said on Friday.
"The launch of the heavy class rocket Angara-A5 within the framework of flight tests confirmed the possibility of putting in space payloads of up to 23 tonnes," he said.
Under the 2020 program for launches Russia’s Aerospace Forces in the 4th quarter of last year orbited space satellites Glonass-K and a cluster of three space satellites Gonets-M using Soyuz-2.1b rockets.

Teen Interning at NASA Discovered a New Planet Which Orbits Two Stars
During the summer of 2019, a 17-year-old high school student named Wolf Cukier arrived at NASA's Goddard Space Flight Center ready for a summer of learning at their new prestigious, coveted internship. He was put in charge of examining data collected by the Transiting Exoplanet Survey Satellite (TESS), which searches the universe for systems with two stars.
TOI-1338 b is considered a Neptune-like gas exoplanet, about 6.9 times larger than Earth. An exoplanet is a planet outside of our solar system. This example lies 1,317 light years away from Earth and orbits its two stars roughly every 95 days. Discovery of planets such as TOI-1338 b are a main function of NASA's TESS. The system documents dual-star systems to track the variations in light.
Star System With Five Wildly Different Planets Orbiting In Harmony Discovered | IFLScience

An international team of astronomers has discovered an incredible star system. Six planets orbit star TOI-178 and the outer five orbit in perfect harmony, a phenomenon known as resonance. Other planetary systems have been seen to be in resonance but this is the first time the planets involved are so wildly different from one another.

Temperature Management in Space
The universe is merciless and infinite, and satellites orbiting the earth are witnessing this first hand. Extreme temperature differences between the side of the earth facing towards and away from the sun pose a significant challenge for orbiting satellites, and because repair or maintenance of active satellites is impossible, the satellite, its components and materials must undergo extensive testing, including temperature and vacuum resistance.
Vacuum and temperature extremes place immense demands on both technology and materials. For example, the moon sees temperatures of up to +120 °C during the long solar phase, while it becomes subject to temperatures as low as -130 °C in the shadow phase.
