Using NASA’s Chandra and ESA’s XMM-Newton space observatories, Indian astronomers have explored the population of ultraluminous X-ray sources in the galaxy NGC 5813, which resulted in the detection of a new source of this type. […]

Astrobiology poses fundamental questions about life in the universe: How did it emerge? Is there life beyond Earth? In a recently published study in PLOS One, researchers from Leiden University investigated how the field was […]

The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our solar system because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water […]

What do many baked goods and the planet Mercury have in common? They shrink as they cool. Evidence suggests that since it formed about 4.5 billion years ago, Mercury has continuously contracted as it has […]

Between 50 and 100 kilometers (30–60 miles) above the Earth’s surface lies a largely unstudied stretch of the atmosphere, called the mesosphere. It’s too high for airplanes and weather balloons, too low for satellites, and […]

A Ph.D. student and his supervisor have developed a simple way to test for active life on Mars and other planets using equipment already on the Mars Curiosity rover and planned for future use on […]

Using the James Webb Space Telescope (JWST), astronomers have observed a young brown dwarf known as Cha Hα 1. As a result, they found that the disk around this brown dwarf is hydrocarbon-rich. The finding […]

New research has uncovered compelling evidence that water from a comet is strikingly similar to that found in Earth’s oceans, offering fresh support for the idea that comets may have played a crucial role in […]

One of the best places to study stars is inside “open clusters,” which are groups of stars that formed together from the same material and are bound together through gravity.This post was originally published on […]

An international team of astronomers using NASA’s IXPE (Imaging X-ray Polarimetry Explorer), has challenged our understanding of what happens to matter in the direct vicinity of a black hole.This post was originally published on this […]
