By reconstructing stellar orbits using real Milky Way stars with accurately determined parameters, the team quantified the galaxy's mass-weighted chemical abundances and age structure. This ...

The SMITHSONIAN ASTROPHYSICAL OBSERVATORY is a part of the Smithsonian Institution which, in conjunction with the Harvard ...

After over a decade of stellar service, ESA’s Gaia spacecraft has been retired – but its legacy is just beginning. From ...

The instrument seeks out planets by detecting the subtle wobble of stars as the gravity of orbiting planets tug on their stellar hosts, known as the radial velocity technique. Using MAROON-X ...

They discovered a surprising number of very old stars in thin disk orbits; the majority of these ... the number of stars with ...

Young, close-orbiting exoplanets known as sub-Neptunes may form farther from their stars and migrate inward or lose their ...

Scientists at the Simulation and Data Lab Astronomy and Astrophysics at Forschungszentrum Jülich have carried out more than 3,000 computer simulations to find the cause of the unusual orbits of ...

The cluster, full of more than 2,500 newborn stars that blaze blue in the Hubble image, is in a galaxy with far fewer heavy chemical substances than the Milky Way. It's mostly made of hydrogen and ...

There are multiple orbits coexisting in our universe. The Earth orbits the Sun within the Solar System. Our Solar System is part of the Milky Way galaxy, which itself orbits a huge black hole at ...

TL;DR: Bring deleted files back from the dead with a 10-year license to a Stellar Data Recovery Professional Plan, now $89.99 (reg. $199). What's worse than accidentally deleting an important file?

The measurements of stellar brightness over time are called ... dips to extract information about the shape of the planets' orbits. One of the most challenging aspects of this project was ensuring ...
