Scientists have developed a way of reading the universe's 'cosmic barometer' to learn more about ancient violent events in space. Exploding stars, random impacts involving comets and meteorites, and even near misses between two bodies can create regions of great heat and high pressure.

Using the telescope network ALMA, astronomers have been able to determine the positions of more than 100 of the most prolific galaxies with unprecedented accuracy. The exact positions could help to solve the mystery of the supposedly extremely high star formation rates: Accordingly the amount of radiation released is not from one but from several galaxies - each of which have more moderate star formation rate and in accordance with theoretical models.

A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward understanding the origin of cosmic rays, one of Fermi's primary mission goals.

The disk surrounding the young star TW Hydrae is regarded as a prototypical example of planetary nurseries. Due to its comparatively close proximity of 176 light-years, the object plays a key role in cosmological birth models. Using the Herschel Space Telescope, researchers including Thomas Henning from the Max Planck Institute for Astronomy in Heidelberg have, for the first time, determined the mass of the disk very precisely.

Peering deep into the dim edges of a distorted pinwheel galaxy in the constellation Ursa Major (the Great Bear), astronomers at Case Western Reserve University and their colleagues have discovered a faint dwarf galaxy and another possible young dwarf caught before it had a chance to form any stars.

Comets trailing wispy tails across the night sky are a beautiful byproduct of our solar system’s formation, icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble.
