Astronomers are using these observations to learn more about how the black hole in the center of the Milky Way galaxy — known as Sagittarius A * (Sgr A* for short) — interacts with, and feeds off, its environment some...

In this particular snapshot, a science discovery followed the release of a Hubble observation of a striking example of a deep-space optical phenomenon dubbed an "Einstein ring." The photo was released in December 2020 as...

When NASA's James Webb Space Telescope begins science operations in 2022, one of its first tasks will be an ambitious program to map the earliest structures in the universe...

For 30 years, astrophysicists have predicted such a slowdown, but this is the first time it has been measured.

These results suggest, then, that there is a particular coupling between the black holes and their galaxies, by which they can expel matter to great distances from the galactic centres, and can even affect the evolution of...

What, precisely, is happening at its core to cause all this activity? Upcoming observations led by Nora Lützgendorf and Macarena García Marín of the European Space Agency using NASA's James Webb Space Telescope will allow...

Located 12 million light-years from Earth in the constellation Ursa Major, the Cigar galaxy is undergoing an exceptionally high rate of star formation called a starburst...

Interacting galaxies, such as these, are so named because of the influence they have on each other, which may eventually result in a merger or a unique formation...

March 19, 2020 One of the biggest ideas in physics is the possibility that all known forces, particles, and interactions can be connected in one framework...

From NASA Dec. 31, 2019 Galactic Pyrotechnics From 23 Million Light Years Away A galaxy about 23 million light years away is the site of impressive, ongoing fireworks. Rather than paper, powder and fire, this galactic light...

From NASA Dec. 20, 2019 This image from the NASA/ESA Hubble Space Telescope shows IC 2051, a galaxy in the southern constellation of Mensa (the Table Mountain) lying about 85 million light-years away. It is a spiral galaxy,...

From NASA Dec. 13, 2019 Hubble Views Galaxy’s Dazzling Display The galaxy is the eponymous member of the NGC 3175 group, which has been called a nearby analog for the Local Group. The Local Group contains our very own home...

From NASA Oct. 24, 2019 Hubble Finds Medusa in the Sky Often referred to by its somewhat drier New General Catalogue designation of NGC 4194, this was not always one entity, but two. An early galaxy consumed a smaller gas-rich...

Spitzer Space Telescope, Milky Way Galaxy, center

From NASA May 3, 2019 Few of the universe’s residents are as iconic as the spiral galaxy. These limelight-hogging celestial objects combine whirling, pinwheeling arms with scatterings of sparkling stars, glowing bursts...
