For the past decade, scientists have been trying to get to the bottom of what seemed like a major inconsistency in the universe. The universe expands over time, but how fast it’s expanding has seemed […]

In the cold, dark outskirts of planetary systems far beyond the reach of the known planets, mysterious gas giants and planetary masses silently orbit their stars—sometimes thousands of astronomical units (AU) away. For years, scientists […]

The James Webb Space Telescope’s deepest view of a single target yet depicts spinning arcs of light that are galaxies from the universe’s distant past, the European Space Agency said Tuesday.This post was originally published […]

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer per second squared. Astrophysicist Kyu-Hyun […]

Using the Hubble Space Telescope (HST), astronomers have observed a globular cluster known as NGC 1754 as part of a systematic study of the most massive and compact clusters in the Large Magellanic Cloud (LMC). […]

The sun’s corona—the outermost layer of its atmosphere, visible only during a total solar eclipse—has long intrigued scientists due to its extreme temperatures, violent eruptions, and large prominences. However, turbulence in Earth’s atmosphere has caused […]

Using the James Webb Space Telescope (JWST), astronomers from Johns Hopkins University (JHU) and elsewhere have detected water ice in a debris disk around HD 181327—a young star located within 160 light years away from […]

When astronomers announced last month they might have discovered the most promising hints of alien life yet on a distant planet, the rare good news raised hopes humanity could soon learn we are not alone […]

A large team of astronomers and astrophysicists affiliated with several institutions in China has discovered a binary star system, where one of the stars is a millisecond pulsar and the other is made mostly of […]

The stately and inclined spiral galaxy NGC 3511 is the subject of this NASA/ESA Hubble Space Telescope image. The galaxy is located 43 million light-years away in the constellation Crater (The Cup). From Hubble’s vantage […]
