Testing mini-radar to peer inside asteroid

A specially upgraded radio-frequency chamber in ESA's technical heart is testing what is set to become the smallest radar system to be flown in space, hosted aboard a breadbox-sized spacecraft.

Indian astronomers investigate X-ray binary GRS 1915+105

Using the AstroSat spacecraft, astronomers from India have observed an X-ray binary system known as GRS 1915+105. The satellite allowed the researchers to conduct a comprehensive study of this object, yielding essential information ...

Blackhole with warped accretion disc discovered

An international team of astrophysicists from South Africa, the UK, France and the US have found large variations in the brightness of light seen from around one of the closest black holes in our Galaxy, 9,600 light-years ...

Gravitational self-lensing of massive black hole binaries

A "massive" black hole (MBH) is one whose mass is more than about one hundred thousand solar-masses. MBHs reside at the centers of most galaxies, and when they actively accrete gas and dust onto their surrounding hot disk ...

Binary stars boost cosmic carbon footprint

The cosmic origin of carbon, a fundamental building block of life, is still uncertain. Massive stars play an important role in the synthesis of all heavy elements, from carbon and oxygen to iron and so on. But even though ...

First ALMA animation of circling twin young stars

Researchers analyzed the accumulated data from the Atacama Large Millimeter/submillimeter Array (ALMA) and depicted the motion of a young twin star system XZ Tauri over three years. This first-ever "ALMA Animation" of twin ...
