Hubble captures massive dead disk galaxy that challenges theories of galaxy evolution

(NASA/Goddard Space Flight Center) By combining the power of a 'natural lens' in space with the capability of NASA's Hubble Space Telescope, astronomers made a surprising discovery -- the first example of a compact yet massive, fast-spinning, disk-shaped galaxy that stopped making stars only a few billion years after the big bang.

A new virtual approach to science in space

(Arizona State University) ASU professor and colleagues suggest a new approach to scientific exploration that they call exploration telepresence.

A new virtual approach to science in space

When Apollo astronauts on the Moon spoke with Mission Control on Earth, there was a noticeable time gap between a statement from Tranquility Base and its immediate acknowledgment from Houston. The gap lasted almost three seconds, or ten times longer than human reaction times would account for.

Radioactive elements in Cassiopeia A suggest a neutrino-driven explosion

Stars exploding as supernovae are the main sources of heavy chemical elements in the Universe. In particular, radioactive atomic nuclei are synthesized in the hot, innermost regions during the explosion and can thus serve as probes of the unobservable physical processes that initiate the blast.
