Astronomy and Space

Astronomy is one of the oldest branches of science. It fascinated humans from the earliest times. Using telescopes and satellites people observe the skies, as well as theoretical and simulation work.

Astronomy and Space Science.

Astronomers study how the Universe began and evolved to its present state, how galaxies form and why our solar system looks as it does.Astronomers and space scientists at the universities around the world are one of the world’s best, working on answers to these and other questions identified in science challenges.

A nearby system hosts the first Earth-sized planet discovered by NASA's Transiting Exoplanets Survey Satellite, as well as a warm sub-Neptune-sized world, according to a new paper from a team of astronomers that includes Carnegie's Johanna Teske,...

For decades, scientists have speculated about the origin of the electromagnetic radiation emitted from celestial regions that host black holes and neutron stars—the most mysterious objects in the universe. Astrophysicists believe that this high-energy...
A volunteer working with the NASA-led Backyard Worlds: Planet 9 project has found the oldest and coldest known white dwarf -- an Earth-sized remnant of a Sun-like star that has died -- ringed by dust and debris....
This artist's impression shows the Milky Way as it may have appeared 6 million years ago during a "quasar" phase of activity. A wispy orange bubble extends from the galactic center out to a radius of about 20,000 light-years....
A Semipalmated Sandpiper wears a geolocator that allows researchers to track its migratory movements. Credit: B. Winn Understanding and managing migratory animal populations requires knowing what's going on with them during all stages of their annual cycle -- and how those...
The data used in this image were taken with Hubble’s Advanced Camera for Surveys in September 2015.Credits: NASA, ESA, STScI, K. Sandstrom (University of California, San Diego), and the SMIDGE team NASA’s Hubble Space Telescope captured two festive-looking nebulas, situated...
While on COVID lockdown, a University of Sydney honours student has written a research paper on a star system dubbed one of the "exotic peacocks of the stellar world". Only one in a hundred...
Some relationships are written in the stars. That's definitely the case for supermassive black holes and their host galaxies, according to a new study from Yale University. The "special relationship" between supermassive black holes (SMBHs) and...
An artist's rendering of an exoplanet is shown. An exoplanet is a planet that exists outside Earth's solar system. Credit: NASA/Ames/JPL-Caltech Is there anybody out there? The question of whether Earthlings are alone in the universe has puzzled everyone from...
Comets delivered carbon to rocky planets, and an icy visitor from the edge of our solar system hurtled past Earth in early 2016 to shed the light on that concept. It briefly became visible to stargazers as...
