Astronomers have discovered a likely explanation for a fracture in a huge cosmic "bone" in the Milky Way galaxy, using NASA's Chandra X-ray Observatory and radio telescopes.

Scientists operating at the quantum level struggle with the pervasive challenge of cosmic rays, which are high-energy ...

When cosmologists used different ways to measure the value of sigma 8, a number that denotes how clumpy the universe is, they ...

Yet its true nature remains a mystery. Scientists have mapped the cosmic composition through studies on cosmic microwave background radiation, supernova explosions, gravitational waves, and baryon ...

The dark nebula is part of the Circinus West molecular cloud, which stretches for 180 light-years, containing a mass 250,000 ...

Research done by the Atacama Cosmology Telescope (ACT) project produced the clearest and most accurate images of the universe ...

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment ...

A new study suggests the universe might be slowly rotating, completing a full revolution every 500 billion years. This subtle ...

The cosmic microwave background (CMB) is the oldest light in the Universe, emitted approximately 380,000 years after the Big Bang. It is microwave radiation that uniformly fills space, a witness to ...

These halos are typically too faint to be seen by normal methods. So instead, the team measured how much the gas dimmed or ...

It's a discrepancy between two methods of measuring the universe’s expansion—supernovae observations versus cosmic background radiation data. Q2: Is the universe's rotation detectable now? Not ...

Background: Galactic cosmic radiation (GCR) is a naturally occurring environmental radiation that originates from outer space. GCR is modulated by solar activity, and its intensity increases with ...
