Astronomy & Astrophysics 101: Circumstellar Disc
What Is a Circumstellar Disc? Circumstellar discs are discs of dust, gas, asteroids and other objects that rotate around a star. Circumstellar discs around newly…

The High Time Resolution Universe Pulsar Survey Double neutron star (DNS) systems in tight orbits are fantastic laboratories to test Einstein’s general theory of relativity….
NASA’s FERMI Satellite Hunts for Extremely Long-wavelength Gravitational-Wave Signals Coalescing supermassive black holes in the centers of merging galaxies fill the universe with low-frequency gravitational…
An international effort led by astrophysicists at the Niels Bohr Institute, University of Copenhagen, and the Technical University of Denmark, have identified a distant object…
Nova outbursts are apparently a source for cosmic rays. The MAGIC telescopes have observed the nova RS Ophiuchi shining brightly in gamma rays at extremely…
What Is a Black Hole? Black holes are objects so dense, and with so much mass, that even light cannot escape their gravitational pull. Black…
Bizarre, Evolutionary Missing Link Uncovered in Hubble Deep Survey of Galaxies The universe is so saturated with galaxies that even the weirdest things can go…
A new study by an international team of astrophysicists, led by the Jodrell Bank Centre for Astrophysics has presented the amazing new discovery of a…
Our universe is a chaotic sea of ripples in space-time called gravitational waves. Astronomers think waves from orbiting pairs of supermassive black holes in distant…
The finding hints at exotic black hole behaviors. In the last seven years, scientists at the LIGO-Virgo Collaboration (LVC) have detected 90 gravitational waves signals….
The ongoing success of the multi-instrument optics alignment for NASA’s Webb telescope’s near-infrared instruments has moved the attention of the commissioning team to chill as…
Hubble spots most distant single star ever seen, at a record distance of 28 billion lightyears. With a fortuitous lineup of a massive cluster of…
Arase satellite uncovers coupling between plasma waves and charged particles in Geospace Scientists unravel a bit more of the mystery underlying how wave-particle interactions generate…
Most stars in spiral galaxies form within the galaxy’s arms. Building the “skeletons” of these galaxies are galactic bones, long filaments that outline the densest…
What Is the Big Bang? The Big Bang is the popular name for the moment in time when the Universe started. The term ‘Big Bang’…
“The Mid-Infrared Instrument (MIRI) and other Webb instruments have been cooling by radiating their thermal energy into the dark of space for the bulk of…
The NASA/ESA Hubble Space Telescope has directly photographed evidence of a Jupiter-like protoplanet forming through what researchers describe as an “intense and violent process.” This…
The MeerKAT telescope in South Africa has discovered a strong radio-wave laser known as a ‘megamaser.’ At nearly five billion light-years from Earth, the record-breaking…
