In 1929, Edwin Hubble published observations that galaxies' distances and velocities are correlated, with the distances determined using their Cepheid stars. Harvard astronomer Henrietta ...

It's like a small oasis in the middle of the cosmos — or at least for those who look to it.

The Kuiper Belt is a disk of small icy bodies, thought to be remnants of the early Solar System, that circles the Sun from the orbit of Neptune (about 30 astronomical units, AU, from the ...

Cambridge, MA -- By taking advantage of a natural lens in space, astronomers have captured an unprecedented look at X-rays from a black hole system in the early universe. This magnifying...

Magnetic fields in space are sometimes called the last piece in the puzzle of star formation. They are much harder to measure than the masses or motions of star-forming clouds, and their ...

Cambridge, MA -- In 2019, astronomers spotted something incredible in our backyard: a rogue comet from another star system. Named Borisov, the icy snowball traveled 110,000 miles per hour...

Every massive galaxy is believed to host a supermassive black hole (SMBH) at its center. Its mass is correlated with the mass of the inner regions of its host (and also with some other pr...

In 2017, the world for the first time observed an interstellar object, called ‘Oumuamua, that was briefly visiting our Solar system. Based on astronomical observations, ‘Oumuamua turned o...

Over the past two decades, very high energy gamma ray emission has been detected coming from the direction of the Milky Way's Galactic Center. The Galactic Center hosts many potential sit...
