Pulsars: New Access to the Universe
Precise as a clock: pulsars in the Milky Way form large-scale observatory for gravitational waves. Astronomical observatories are usually based on Earth and study the extreme processes in the universe…
Asteroid named after Portuguese astrophysicist
Image of asteroid 243 Ida, taken by the Galileo spacecraft. Despite being about ten times larger than asteroid 32599 Pedromachado, 243 Ida is also found in the Asteroid Belt. Credit:…
Webb detects most distant active supermassive black hole to date
The graphic shows the redshift of one active supermassive black hole. At top right is the complete NIRCam image of the field, which has an uneven white outline and is…
Light supergiant reveals a missing evolutionary stage
Artist’s impression of the discovered massive binary system consisting of a stripped star in the background and a Be star in the foreground. Although the stripped star appears bigger, it…
‘Chorus’ of Gravitational Waves Found
Gravitational waves, ripples in the fabric of time-space predicted by Albert Einstein more than a century ago, are permeating the universe at low frequencies, according to a multiyear National Science…
Quasar disks could host black hole collision events
The key stages of the binary formation mechanism highlighted in the cartoon as snapshots from their moment in the simulations. The first panel shows the “mini”-discs around the isolated black…
New Gravitational Waves Observation Run: More Secrets of the Universe
Scientists claim that a new observation run to search for ripples in space-time generated by colliding black holes and other extreme cosmic events will take gravitational wave astronomy to the…
Gravitational Waves Detected as Cosmic ‘Hum’
A 15-year collaboration in which Cornell astrophysicists have played leading roles has found the first evidence of gravitational waves slowly undulating through the galaxy, ripples in space-time likely generated by…
This Planet Survived Death Sentence – Nobody Knows How
Stars tend to get violent when they’re about to die. And it is not easy for the planets that orbit them. Take our Sun, for example: in about 5 billion…
