Cassiopeia A, or Cas A for short, is one of the most well studied supernova remnants in our galaxy. But it still holds major surprises.

A five-year analysis of an event captured by a tiny telescope at McDonald Observatory and followed up by telescopes on the ground and in space has led astronomers to believe they witnessed a giant black hole tear apart a star.
The NASA/ESA Hubble Space Telescope has captured this striking view of spiral galaxy NGC 7714.
An international team of astronomers led from Chalmers has used the giant radio telescope LOFAR to create the sharpest astronomical image ever taken at very long radio wavelengths.
In this image the NASA/ESA Hubble Space Telescope takes a close look at the spiral galaxy NGC 4217, located 60 million light-years away from Earth. The galaxy is seen almost perfectly edge on and is a perfect candidate for studying the nature of extraplanar dust structures -- the patterns of gas and dust above and below the plane on the galaxy, seen here as brown wisps coming off NGC 4217.
Sometimes it takes a village to find new and unusual objects in space.
NASA's Dawn spacecraft has returned the sharpest images ever seen of the dwarf planet Ceres. The images were taken 147,000 miles (237,000 kilometers) from Ceres on Jan. 25, and represent a new milestone for a spacecraft that soon will become the first human-made probe to visit a dwarf planet.
Astronomers poring over four years of data from NASA's Kepler spacecraft have discovered a star that's 11.2 billion years old and has at least five Earth-size planets.
Astronomers at the Leiden Observatory and the University of Rochester have discovered that the ring system that they see eclipse the very young Sun-like star J1407 is of enormous proportions, much larger and heavier than the ring system of Saturn.
Based on the latest evidence and theories our galaxy could be a huge wormhole (or space-time tunnel; have you seen "Interstellar?") and, if that were true, it would be "stable and navigable."
The subject of this image is NGC 6861, a galaxy discovered in 1826 by the Scottish astronomer James Dunlop.
On Thursday, January 8, members of the Hubble Space Telescope Mission presented mission status and upcoming plans in a Town Hall at the 225th American Astronomical Society meeting.
NASA's Kepler Space Telescope, despite being hobbled by the loss of critical guidance systems, has discovered a star with three planets only slightly larger than Earth.
Last week, at the 225th meeting of the American Astronomical Society, members of the James Webb Space Telescope mission held a town hall to update members of the status and progress of the mission.
Orbiting the Earth 353 miles above the ground, the Hubble Space Telescope silently pivots toward its new target. At the same time, flying 93 million miles away in interplanetary space, NASA's Spitzer Space Telescope receives commands to point itself at the same celestial target.
The first ever contest allowing members of the public to name ExoWorlds begins its first round today, offering the registered clubs and non-profit organisations the chance to nominate their favourite systems to take through to the next rounds.
If you sweep a laser pointer across the Moon fast enough, you can create spots that actually move faster than light. Anyone can do it.
By analyzing the light of hundreds of thousands of celestial objects, Johns Hopkins astronomers from the Sloan Digital Sky Survey (SDSS) have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars.
