Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?This […]

Astronomers have reported the discovery of an unusual X-ray transient detected by the Einstein Probe that does not fit any known class of cosmic explosions. The paper presenting its multiwavelength analysis was published in the […]

Research led by the Tata Institute of Fundamental Research, Mumbai, along with Professor Subir Sarkar from the University of Oxford, questions the widely accepted argument that the expansion rate of the universe is accelerating and […]

There are multiple ways to form black holes. The one most commonly taught in high school physics classes is that they are created from the collapse of a dying star. But there is another class […]

Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what […]

Astronomers have used the James Webb Space Telescope to catch an extraordinary glimpse of a massive galaxy taking shape in the early universe. They identified a compact group of at least six galaxies that are […]

Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as carbon […]

Astronomers have discovered a “remarkable” bow-and-arrow-shaped radio galaxy with an enormous arc-like structure extending nearly 1.8 million light-years across. The newly identified system, detailed in a new paper published today in Monthly Notices of the […]

Using the Multi Unit Spectroscopic Explorer (MUSE) and the Manchester Echelle Spectrograph (MES), astronomers from Turkey and Mexico have investigated a planetary nebula discovered two centuries ago, known as NGC 6563. Results of the observations, […]

A stunningly concentrated and hefty galaxy cluster, from a time in the universe’s history when such massive structures aren’t expected to have fully formed yet, is challenging cosmic evolution theories. Across a series of three […]
