Variable Star

Scientists have gotten the best-ever view of 'space tornadoes' howling near the Milky Way's black hole. The cosmic twisters could play an important role in distributing organic molecules throughout the galaxy.

The James Webb Space Telescope has spotted a 'rogue' cosmic object barrelling through our galaxy without a star, and covered in clouds of iron and magnesium minerals.

New observations from the NASA/ESA/CSA James Webb Space Telescope support the presence of three specific features in the atmosphere of the rapidly rotating, free-floating planetary-mass object SIMP J013656.5+093347.

As our Solar System orbits the Milky Way, it encounters various environments, including dense regions of the interstellar medium.

White dwarfs may present amenable environments for life on planets formed within or migrated to their habitable zones, generating warmer surface environments than those of planets with main-sequence host stars, according to new research from the University of California, Irvine.

A type Ia supernova event called SN 2022abvt was discovered two years ago in the spiral galaxy LEDA 132905.

In 2018, astronomers observed that the corona of 1ES 1927+654, an actively accreting, 1.4-million-solar-mass black hole located in a galaxy around 270 million light-years away, suddenly disappeared, before reassembling months later.

A newly discovered neutron star is behaving so strangely that it may alter our understanding of the dense remains left behind when stellar objects die

NASA has released a beautiful photo taken by the NASA/ESA Hubble Space Telescope of the spiral galaxy LEDA 22057.

Betelgeuse, also known as Alpha Orionis or Alpha Ori, is the second-closest red supergiant to Earth.

Astronomers using the NASA/ESA Hubble Space Telescope have made a unique timelapse of R Aquarii's dynamic behavior from observations spanning from 2014 to 2023.

Cosmologists might have to go back to the drawing board.

Astronomers have detected an exoplanet around Barnard's star, one of the sun's closest neighbours, but it is too hot for liquid water or life

Betelgeuse having a binary counterpart would explain some of its perceived patterns of brightness.

For the 1st time, astronomers have watched a star's surface bubble in magnificent detail. The bubbling is hot gases on a star 178 light-years away. The post Watch a star's surface bubble in fantastic video and images first appeared on EarthSky.

Using the Gemini Observatory, Argentinian astronomers have conducted comprehensive photometric and spectroscopic observations of an early-type dwarf galaxy known as CGCG014-074. Results of the observational campaign, published September 3 in the Monthly Notices of the Royal Astronomical Society, shed more light on the properties and evolution of this galaxy.

Chinese astronomers have conducted multi-frequency polarimetric observations of a quasar known as 1604+159. Results of the observational campaign, published August 13 on the pre-print server arXiv, shed more light on the properties of this quasar, including its morphology and magnetic field.

Astronomers using the James Webb Space Telescope have found that Ariel, a moon of Uranus, has some of the most carbon dioxide-rich deposits in the solar system, hinting at a buried water ocean.

A "guest star," briefly seen in 1181, was created by colliding dead stars, according to new simulations that may finally solve an 800-year-old cosmic mystery.

The cosmos is dark. The Lilly-Madau diagram reveals that it will become much darker still
