The direct detection of gravitational waves from at least five sources during the past two years offers spectacular confirmation of Einstein’s model of gravity and…
The spots on the surface of the Sun come and go with an 11-year periodicity known as the solar cycle. The solar cycle is driven…
This visualization shows the motion of one electron in the magnetic reconnection region. As the spacecraft approaches the reconnection region, it detects first high-energy particles,…

At first glance, it would seem to be impossible to look inside a star. An international team of astronomers, under the leadership of Earl Bellinger…
Young galaxies blaze with bright new stars forming at a rapid rate, but star formation eventually shuts down as a galaxy evolves. A new study,…
Astronomers from the Harvard-Smithsonian Center For Astrophysics have measured the sizes of the accreting regions around the supermassive black holes in four distant AGN using…
A new project using data from NASA’s Chandra X-ray Observatory and other telescopes allows people to navigate through real data of the remains of an…
Despite the many impressive discoveries humans have made about the universe, scientists are still unsure about the birth story of our solar system. Scientists at…
Astronomers studying the Toothbrush Cluster with new radio observations combined with other wavelengths have been able to confirm the galaxy merger scenario and estimate the…
New research has provided a deeper insight into emission line galaxies, used in several ongoing and upcoming surveys, to help us further understand the composition…
Using ESO’s Very Large Telescope, astronomers have for the first time directly observed granulation patterns on the surface of a star outside the Solar System…
The center of our Galaxy has been intensely studied for many years, but it still harbors surprises for scientists. A snake-like structure lurking near our…
An international team of scientists reveals in the journal Nature that the neutron-star merger announced in October has solved one mystery, where gold comes from,…
An innovative interpretation of X-ray data from a cluster of galaxies could help scientists fulfill a quest they have been on for decades: determining the…
Far from earth, two black holes orbit around each other propagating waves that bend time and space. The existence of such waves — gravitational waves…
A new Chandra image shows the location of several elements produced by the explosion of a massive star. Supernova remnants and the elements they produce…
