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 new study disputes the prevailing hypothesis on why Mercury has a big core relative to its mantle. For decades, scientists argued that hit-and-run collisions blew away much of Mercury's rocky mantle and left the big, dense,...
Japanese astronomers have developed a new artificial intelligence (AI) technique to remove noise in astronomical data due to random variations in galaxy shapes. After extensive training and testing on large mock data created by supercomputer simulations, they...
Our universe is expanding, but our two main ways to measure how fast this expansion is happening have resulted in different answers. For the past decade, astrophysicists have been gradually dividing into two camps: one that believes...
Astronomers have found a stellar corpse often called a white dwarf that’s roughly the scale of Earth’s moon. White dwarfs are the collapsed remnants of stars that were once about eight times the mass of our Sun...
New findings from a team using the international Gemini Observatory and the WIYN 3.5-meter Telescope at Kitt Peak National Observatory suggest that Earth-sized worlds could be lurking undiscovered in binary star systems.Some exoplanet searches could be missing...
Analysing images from the Hubble and Spitzer Space Telescopes, the researchers calculated the age of these galaxies as ranging from 200 to 300 million years, allowing an estimate of when their stars first formed.
A cluster of comet fragments believed to have hit Earth nearly 13,000 years ago may have shaped the origins of human civilisation, research suggests. Possibly the most devastating cosmic impact since the extinction of...
Research shows that certain galaxies deviate from foundation theories of gravity. Scientists are looking into the possibility of relearning gravity in order to understand the universe. For many years now, astronomers and physicists have...
The most accurate distance measurement yet of ultra-diffuse galaxy (UDG) NGC1052-DF2 (DF2) confirms beyond any shadow of a doubt that it is lacking in dark matter. The newly measured distance of 22.1 +/-1.2 megaparsecs are based on...
A team of astronomers have now published new images of the star’s surface, taken using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), that clearly show how its brightness changed. The new research reveals that the...
Galaxies reside in filaments hundreds of millions of light-years long, on a backbone of dark matter. And, where those filaments meet, there are galaxy clusters. Between them are massive voids, where galaxies are sparse. A team of...
