(University of Arizona) Astronomers from the California Institute of Technology and the University of Arizona have released the largest data set ever collected that documents the brightening and dimming of stars and other celestial objects – 200 million in total.

(NASA/Goddard Space Flight Center) Using NASA’s Hubble Space Telescope, astronomers have solved a longstanding mystery on the type of star, or so-called progenitor, which caused a supernova seen in a nearby galaxy. The finding yields new observational data for pinpointing one of several scenarios that trigger such outbursts.

(Vanderbilt University) The smallest exoplanets yet discovered orbit a dwarf star almost identical to Barnard’s star, one of the sun’s nearest neighbors. The similarity helped the astronomers calculate the size of the distant planets.

• NASA’s Hubble Breaks New Ground With Distant Supernova Discovery
  NASA’s Hubble Space Telescope has looked deep into the distant universe and detected the feeble glow of a star that exploded more than 9 billion years ago.

(ESA/Hubble Information Centre) Using the NASA/ESA Hubble Space Telescope, astronomers have uncovered a cluster of galaxies in the initial stages of development, making it the most distant such grouping ever observed in the early universe.

(NASA/Goddard Space Flight Center) Using observations from NASA’s Rossi X-ray Timing Explorer satellite and the National Science Foundation’s Very Long Baseline Array radio telescope, an international team of astronomers has identified the moment when a black hole in our galaxy launched super-fast knots of gas into space.
