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:…

Researchers at the University of Toronto have revealed a theoretical breakthrough that may explain the nature of invisible dark matter and the universe’s large-scale structure known as the cosmic web.…

Scientists have discovered a pair of gravitationally bound quasars inside two merging galaxies that existed when the universe was just 3 billion years old. An international group of researchers, including…

Scientists are reporting the first evidence that our Earth and the universe around us are awash in a background of spacetime undulations called gravitational waves. The waves oscillate very slowly…

Mercury is the least explored rocky planet of the Solar System, with one of the main reasons being that getting there is really difficult. As BepiColombo gets closer to the…
