Source of Mysterious ‘Fast’ Radio Signals Pinpointed, But What Is It?

For about 10 years, radio astronomers have been detecting mysterious milliseconds-long blasts of radio waves, called “fast radio bursts” (FRB). While only 18 of these events have been detected so far, one FRB has been particularly intriguing as the signal has been sporadically repeating. First detected in November 2012, astronomers didn’t know if FRB 121102 […]

Distant Stellar Nurseries: This Time, in High Definition

This article is a guest post by Anna Ho, who is currently doing research on stars in the Milky Way through a one-year Fulbright Scholarship at the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany. In the Milky Way, an average of seven new stars is born every year. In the distant galaxy GN20, […]

Astronomers Poised to Capture Image of Supermassive Milky Way Black Hole

Scientists have long suspected that supermassive black holes (SMBH) reside at the center of every large galaxy in our universe. These can be billions of times more massive than our sun, and are so powerful that activity at their boundaries can ripple throughout their host galaxies. In the case of the Milky Way galaxy, this […]
