Astronomers find evidence for planets shrinking over billions of years
A team of astronomers led by University of Hawai?i Institute for Astronomy (IfA) graduate student Travis Berger has shown that an intriguing class of Neptune-sized planets shrinks over billions of years.
From centuries of studying the planets within our solar system, astronomers have wondered how planets form and evolve to become the ones we observe them today. One of the most surprising f Astronomers measure enormous planet lurking far from its star
Scientists aren't usually able to measure the size of gigantic planets, like Jupiter or Saturn, which are far from the stars they orbit. But a UC Riverside-led team has done it.
The planet is roughly five times heavier than Jupiter, hence its nickname GOT 'EM-1b, which stands for Giant Outer Transiting Exoplanet Mass. Though it is nearly 1,300 light years away from Earth, GOT 'EM-1b, or Ke Arecibo observatory helps find possible 'first hints' of low-frequency gravitational waves
Data from Arecibo Observatory in Puerto Rico has been used to help detect the first possible hints of low-frequency disturbances in the curvature of space-time.
The results were presented at the 237th meeting of the American Astronomical Society, which was held virtually, and are published in The Astrophysical Journal Letters. Arecibo Observatory is managed by the University of Central Flo New Space Telescope Will Reveal Unseen, Dynamic Lives of Galaxies
NASA has selected the University of Arizona to lead one of its four inaugural Astrophysics Pioneers missions. With a $20 million cost cap, the Aspera mission will study galaxy evolution with a space telescope barely larger than a mini fridge. The telescope will allow researchers to observe galaxy processes that have remained hidden from view until now. Iceye to launch three SAR satellites on SpaceX rideshare flight
SAN FRANCISCO – Iceye is preparing to send three Synthetic Aperture Radar (SAR) satellites into orbit on the SpaceX Falcon 9 small satellite rideshare mission scheduled for launch Jan. 21.
With the upcoming launch, Iceye seeks to expand its constellation to include six SAR satellites.
Energy from solar wind favours the north
Using information from ESA’s Swarm satellite constellation, scientists have made a discovery about how energy generated by electrically-charged particles in the solar wind flows into Earth’s atmosphere – surprisingly, more of it heads towards the magnetic north pole than towards the magnetic south pole.

This Copernicus Sentinel-2 image of Madrid in Spain appears to have been taken in black and white. In fact, it is a true-colour image – but the heaviest snowfall in 50 years has blanketed the region, turning the landscape white. Pool preps

Prepping for a spacewalk typically means diving underwater to rehearse and fine-tune operations.
In 2016, ESA astronaut Alexander Gerst performed such an underwater rehearsal for the Colka high speed radio, the brown box imaged above, that will be installed this month on the International Space Station.
NASA astronauts Mike Hopkins and Victor Glover will integrate the small fridge-sized device outside the European Columbus module during a spacewalk scheduled this year. ESA astronaut Andreas Mogensen will be at NASA’s mission control directing the spacewalkers as Capcom. The Columbus Ka-band terminal, nicknamed ‘Colka’, will enable faster communication with Europe.

WASHINGTON — NASA will start an upgrade this year of the solar arrays of the International Space Station to ensure the station has sufficient power to continue operating at least through the end of the decade.
