60 Minutes in Space March 2015 –Rare Dwarf Galaxies, Mysterious Star-Forming Clusters, Cosmic Lenses, and Colliding Stars

Posted 4/1/2015 12:04 AM by Kim Evans | Comments

For the second half of his presentation, Dimitri focuses outside our galaxy to discuss how scientists discovered two rare dwarf satellite galaxies orbing the Milky Way using data from the Dark Energy Survey.

Moving from dwarf galaxies to star clusters, Dimitri talks about a newly-discovered massive star cluster buried within a supernebula located in the constellation Centaurus.

Next, Dimitri talks about how astronomers using the Hubble space Telescope spotted a distant supernova split into four images by a cosmic lens.

Wrapping up by going back in space and time, he discusses new observations that reveal a bright star observed in 1670 was not a nova but a spectacular collision between two stars.
