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…

IceCube, an Antarctic telescope, has directly observed neutrinos, hard-to-detect subatomic particles, coming from our own galaxy, the Milky Way. For as long as humans have existed, we’ve been able to…

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…

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…

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…

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…

Here’s a story of how an exoplanet named Halla survived the rebellion of its home star Baekdu. When stars, similar to the sun, have reached the end of their lifetime,…

The Milky Way galaxy is an awe-inspiring feature of the night sky, dominating all wavelengths of light and viewable with the naked eye as a hazy band of stars stretching…

The universe is humming with gravitational radiation — a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. Artist’s interpretation of an array of…

Astronomers using data collected by CSIRO’s Parkes radio telescope, Murriyang, have found their strongest evidence yet for low-frequency gravitational waves. CSIRO’s Parkes Radio Telescope, Murriyang, on Wiradjuri Country. Image credit:…
