Cambridge, MA -- Astronomers at the Center for Astrophysics | Harvard & Smithsonian have helped detect the clear presence of a moon-forming region around an exoplanet — a planet outsi...

Cambridge, MA - At radio wavelengths, Centaurus A is one of the largest and brightest objects in the night sky, showing extended jet and giant radio lobes. After it was identified as one...

Astronomers refer to all the elements heavier than helium as "metals," even elements that are typically found in gaseous form. In the big bang only hydrogen and helium (and a trace of lit...

The supermassive black hole at the center of our Milky Way galaxy, Sagittarius A* (“SgrA*), is by far the closest such object to us, about 27 thousand light-years away. Although it is not...

Galaxy clusters are unique laboratories for the study of large-scale magnetic fields. The turbulent intracluster medium is permeated by a ubiquitous magnetic field on scales ranging from ...

Submillimeter galaxies (SMGs) are a class of the most luminous, distant, and rapidly star-forming galaxies known and can shine brighter than a trillion Suns (about one hundred times more ...

The triggering of star formation, and also its quenching, is regulated by young massive stars in galaxies which inject energy and momentum into the interstellar medium. Feedback from the ...

Cambridge, MA - When Betelgeuse, a bright orange star in the constellation of Orion, lost more than two-thirds of its brightness in late 2019 and early 2020, astronomers were puzzled. W...

At the center of our Milky Way lies a supermassive black hole (SMBH) called Sagittarius A* (SgrA*). Supermassive black holes reside at the centers of most galaxies, and when they actively...

Forty years ago astronomers using sensitive new imaging techniques discovered a class of large, faint galaxies they named low surface brightness galaxies. Giant low surface brightness gal...
