Because astronomers had seen these objects primarily in the oldest, most massive galaxies that glow with the red light of aging stars, many thought active…
Crab Pulsar emits light at highest energies ever detected in a pulsar system, scientists report
The VERITAS experiment measured gamma rays coming from the Crab Pulsar at such large energies that they cannot be explained by current scientific models of how…
No time for change: Cosmic weight watching reveals black hole-galaxy history
This pioneering method promises a new approach for studying the co-evolution of galaxies and their central black holes. First results indicate that for…
Light Fantastic: Laser at Inner Harbor Beams Hubble's Heartbeat
Hubble spectral observations of distant galaxies will be projected onto the Maryland Science Center with an intense green laser. Educational activities will…
Black hole, star collisions may illuminate universe's dark side

Small distant galaxies host supermassive black holes
“It's kind of a chicken or egg problem: Which came first, the supermassive black hole or the massive galaxy? This study shows that even low-mass galaxies have…
