In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star, called V838 Monocerotis, has long since faded back to obscurity. But observations by NASA's Hubble Space Telescope of a phenomenon called a "light echo" around the star have uncovered remarkable new features. These details promise to provide astronomers with a CAT-scan-like probe of the three-dime

Two galaxies collide in space. Runner-up, Galaxies The Antennae Galaxies Discovered in 1785 by William Herschel, the Antennae Galaxies are a pair of interacting or colliding galaxies (NGC4038 and NGC4039) whose gravitational fields have disturbed one another. Resembling the antennae of insects, they have been captured by an earthbound telescope and camera that has gathered 75 hours of exposure over the course of 38 nights from January to June 2014.

Asteroids vs. comets: How do they differ, and do they pose a threat to Earth?
Halley's Comet. Photograph by James Balog in 1986. The return of Halley's Comet in my lifetime was not as spectacular as it was in 1910. I did not see it myself, the weather was overcast for most of the period it could be seen in my part of the world.

Is there a "hole" in the universe?
The Eridanus Void. This area shows almost no signs of cosmic matter, meaning no stars, planets, solar systems or clouds of cosmic dust. Researchers couldn't even find dark matter, which is invisible but measurable by its gravitational pull. There were also no signs of black holes that might have gobbled up the matter once present in the region.
