Latest hot gas Stories
The flow of hot gas toward a black hole has been clearly imaged for the first time in X-rays.
Astronomers have caught sight of an unusual galaxy that has illuminated new details about a celestial "sandbar" connecting two massive islands of galaxies.
Observing the X-ray-bright gas in the halo of the Milky Way, ESA's XMM-Newton has gathered new data which favor a process involving fountains of hot gas in our Galaxy.
Surveying the microwave sky, Planck has obtained its very first images of galaxy clusters, amongst the largest objects in the Universe, by means of the Sunyaev-Zel'dovich effect, a characteristic signature they imprint on the Cosmic Microwave Background.
Combining observations made with ESOâ€™s Very Large Telescope and NASAâ€™s Chandra X-ray telescope, astronomers have uncovered the most powerful pair of jets ever seen from a stellar black hole.
Two spectacular tails of X-ray emission have been seen trailing behind a galaxy using the Chandra X-ray Observatory.
We live in a hierarchical Universe where small structures join into larger ones. Earth is a planet in our Solar System, the Solar System resides in the Milky Way Galaxy, and galaxies combine into groups and clusters.
This composite image shows the massive galaxy cluster MACSJ0717.5+3745 (MACSJ0717, for short) where four separate galaxy clusters have been involved in a collision, the first time such a phenomenon has been documented.
This composite image shows M84, a massive elliptical galaxy in the Virgo Cluster, about 55 million light years from Earth.
Right in time for the festive season, ESA's XMM-Newton X-ray observatory has discovered a huge cloud of high-temperature gas resting in a spectacular nearby star-forming region, shaped somewhat like the silhouette of Santa Claus.
