NGC 4302 and NGC 4298
This stunning cosmic pairing of the two very different looking spiral galaxies NGC 4302 and NGC 4298 was imaged by the NASA/ESA Hubble Space Telescope.
An international research team led by Ariel Goobar at Stockholm University has detected for the first time multiple images from a gravitationally lensed Type Ia supernova.
A Swedish-led team of astronomers used the NASA/ESA Hubble Space Telescope to analyse the multiple images of a gravitationally lensed type Ia supernova for the first time.
At the center of the Centaurus galaxy cluster, there is a large elliptical galaxy called NGC 4696. Deeper still, there is a supermassive black hole buried within the core of this galaxy.
Sometimes it takes a lot of trees to see the forest. In the case of the latest discovery made by astronomers at the University of Arizona, exactly 732,225.
In the 1970s, scientists noticed something strange about the motion of galaxies. All the matter at the edge of spiral galaxies was rotating just as fast as material in the inner part of the galaxy.
Although galaxy formation and evolution are still far from being fully understood, the conditions we see within certain galaxies -- such as so-called starburst galaxies -- can tell us a lot about how they have evolved over time.
Researchers at the University of Waterloo have been able to capture the first composite image of a dark matter bridge that connects galaxies together.
A powerful new array of radio telescopes is being deployed for the first time this week, as the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile joins a global network of antennas poised to make some of the highest resolution images that astronomers have ever obtained.
Some astronomical objects have endearing or quirky nicknames, inspired by mythology or their own appearance.
Of all the varieties of exploding stars, the ones called Type Ia are perhaps the most intriguing.
Observations using ESO's Very Large Telescope have revealed stars forming within powerful outflows of material blasted out from supermassive black holes at the cores of galaxies.
The Milky Way's closest neighbor, Andromeda, features a dominant source of high-energy X-ray emission, but its identity was mysterious until now.
Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves.
Berkeley Lab-led research raises new questions about properties of dust in local and distant reaches of Milky Way
Some 290 million years ago, a star much like the sun wandered too close to the central black hole of its galaxy.
A massive protostar, deeply nestled in its dust-filled stellar nursery, recently roared to life, shining nearly 100 times brighter than before.
