The Sun might emit less radiation by mid-century, giving planet Earth a chance to warm a bit more slowly but not halt the trend of…
Extremely distant galaxies are usually too faint to be seen, even by the largest telescopes. But nature has a solution: gravitational lensing, predicted by Albert…
Magnetism plays a critical role in various solar phenomena such as flares, mass ejections, flux ropes, and coronal heating. Sunspots are areas of concentrated magnetic…
Roughly 50 million light-years away lies a somewhat overlooked little galaxy named NGC 1559. Pictured here by Hubble’s Wide Field Camera 3, this barred spiral…
A new international study involving The Australian National University (ANU) has found a plane of dwarf galaxies orbiting around Centaurus A in a discovery that…
The South Pole Telescope (SPT) is a 10-meter-diameter telescope in the Antarctic that has been operating at millimeter- and submillimeter-waves for a decade; the CfA…
A dark cloud of cosmic dust snakes across this spectacular wide field image, illuminated by the brilliant light of new stars. This dense cloud is…
This project, in which the Instituto de Astrofísica de Canarias (IAC) is collaborating, has made a map with 300 galaxies close to the Milky Way,…
An international team of astronomers led by Giuseppina Battaglia, researcher at the Instituto de Astrofísica de Canarias (IAC), finds signs that the outer halo of…
An International team with participation by researchers with close links to the Instituto de Astrofísica de Canarias and the University of La Laguna, obtains the…
The nearby dwarf galaxy known as the Large Magellanic Cloud (LMC) is a chemically primitive place. Unlike the Milky Way, this semi-spiral collection of a…
The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers since they were…
A team of scientists, led by Boy Lankhaar at Chalmers University of Technology, has solved an important puzzle in astrochemistry: how to measure magnetic fields…
There are currently over 3500 confirmed exoplanets known thanks to the remarkable sensitivity of the Kepler spacecraft and to technological advances in space and ground-based…
A new national facility at ESO’s La Silla Observatory has successfully made its first observations. The ExTrA telescopes will search for and study Earth-sized planets…
Just how quickly is the dark matter near Earth zipping around? The speed of dark matter has far-reaching consequences for modern astrophysical research, but this…
The afterglow from the distant neutron-star merger detected last August has continued to brighten – much to the surprise of astrophysicists studying the aftermath of…
