NASA is poised to launch its latest X-ray space telescope on a two-year hunt for hard-to-see objects lurking in the heart of the Milky Way and other galaxies.

An international team of scientists has observed four super-massive black holes at the center of galaxies, which may provide new information on how these central black hole systems operate.

Completing an orbit in less than an Earth day, planet Wasp-18b should have burned up, according to accepted theory. Scientists have discovered a planet that shouldn't exist. The finding, they say, could alter our understanding of orbital dynamics, a field considered pretty well settled since the time of astronomer Johannes Kepler 400 years ago.

It may not be possible to travel back in time, but seeing stars and galaxies as they looked millions or even billions of years ago is no problem thanks to telescopes, the closest thing we have to time machines.

Four galaxies are involved in this pile-up 280 million light years from Earth.
