The most comprehensive view yet of the evolution of the Universe. Hubble Space Telescope observations in the ultraviolet have been added to the existing observations of the Hubble Ultra Deep Field. So the youngest and hottest stars - absent from the original - are now included. (Image Credit: NASA, ESA, H. Teplitz and M. Rafelski (IPAC/Caltech), A. Koekemoer (STScI), R.

At the 2015 World Science Festival, four prominent astrophysicists discussed one of the most troubling (and embarrassing) puzzles in modern physics, and whether a theory of multiple universes can hope to solve it.
This image of a pair of interacting galaxies called Arp 273 was released to celebrate the 21st anniversary of the launch of the NASA/ESA Hubble Space Telescope. The distorted shape of the larger of the two galaxies shows signs of tidal interactions with the smaller of the two. It is thought that the smaller galaxy has actually passed through the larger one.
The Tadpole Galaxy (also known as UGC 10214 or Arp 188) is a disrupted barred spiral galaxy located about 420 million light-years away toward the northern constellation Draco. Its most dramatic features are an incredibly long trail of stars and massive, bright blue star clusters, reflecting the essence of our dynamic, restless and violent Universe. - Credit: NASA, Hubble, Mehdi Bozzo-Rey
New Telescope to Take First-Ever Black Hole Photo - A group of astronomers are meeting this week to plan out an ambitious and unprecedented project — capturing the first-ever image of a black hole. The researchers want to create an Earth-size virtual instrument called the Event Horizon Telescope, a worldwide network of radio telescopes powerful enough to snap a picture of the supermassive black hole at the heart of our Milky Way galaxy.
M 81 (Bode’s Galaxy), M 82 (Cigar Galaxy) and part of IFN, Messier 81 (Bode’s Galaxy or NGC 3031) and Messier 82 (Cigar Galaxy or NGC 3034) are respectively spiral and starburst galaxy about 12 million light-years away in the constellation Ursa Major.This couple is seen through the faint glow of an Integrated Flux Nebulae (or IFN).

Known as Seyfert's Sextet, this intriguing group of galaxies lies in the head portion of the split constellation of the Snake (Serpens). About 190 million light-years away, the interacting galaxies are tightly packed into a region around 100,000 light-years across, comparable to the size of our own Milky Way galaxy, making this one of the densest known galaxy groups. Bound by gravity, the close-knit group may coalesce into a single large galaxy over the next few billion years.
