Rocket experiment redefines what scientists think of as galaxies

NASA's sounding rocket experiment has detected a surprising surplus of infrared light in the dark space between galaxies, a diffuse cosmic glow as bright as all known galaxies combined. The glow is thought to be from orphaned stars flung out of galaxies. The finding

NuSTAR discovers first ultraluminous pulsar, impossibly bright dead star

Astronomers working with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) have found a pulsating dead star beaming with the energy of about 10 million suns. The object, previously thought to be a black hole because it is so powerful, is in fact a pulsar - the

Monster black hole lurking inside one of the tiniest galaxies ever known

A supermassive blackhole has been found inside the tiniest galaxy ever found, the M60-UCD1, located about 54 million light years away from Earth. Researchers used NASA’s Hubble and the Gemini North 8-meter optical and infrared telescope on Hawaii to observe and

An anomaly in satellites' flybys baffles scientists

Scientists have found anomalies in the speed of space probes such as Rosetta and Cassini, as they fly over certain planets, something they haven't been able to explain. Noticed for the first time during a careful inspection of DSN Doppler data shortly after the Eart
