Dark Gulping
(Preview)
Did 'Dark Gulping' Generate Black Holes in Early Universe? A process called 'dark gulping' may solve the mystery of the how supermassive black holes were able to form when the Universe was less than a billion years old. Dr Curtis Saxton will be presenting the study at the European Week of Astronomy an...

Jet trail nebula
(Preview)
Using the NASA Rossi X-ray Timing Explorer (RXTE) satellite, a team of astronomers have discovered an object predicted, but never seen before - a 'jet trail' nebula. Team leader Dr Klaas Wiersema of the University of Leicester will present the discovery on Wednesday 22nd April at the European Week...

NGC 7049
(Preview)
An unusual large galaxy with a shape bordering between spiral and elliptical has been spotted by NASA's Hubble Space Telescope. NGC 7049 sits in the southern constellation Indus, and is the brightest of a cluster of galaxies, a so-called brightest cluster galaxy. Typical BCGs are some of the oldes...

GRB 070714B
(Preview)
Using the powerful one-two combo of NASAs Swift satellite and the Gemini Observatory, astronomers have detected a mysterious type of cosmic explosion farther back in time than ever before. The explosion, known as a short gamma-ray burst (GRB), took place 7.4 billion years ago, more than halfway b...

MAGIC J0223+430
(Preview)
An international team of astrophysicists, involving several research groups in Spain, has discovered a source of very high energy gamma rays in the region of the distant galaxies 3C 66A and 3C 66B. This new gamma emission, observed from the MAGIC telescope in La Palma (Canary Islands) is not consis...

Arp 261
(Preview)
The ESO Very Large Telescope has taken the best image ever of a strange and chaotic duo of interwoven galaxies. The images also contain some surprises - interlopers both far and near. Sometimes objects in the sky that appear strange, or different from normal, have a story to tell and prove scientific...

Hickson Compact Group 90
(Preview)
Though they are the largest and most widely scattered objects in the universe, galaxies do go bump in the night. The Hubble Space Telescope has photographed many pairs of galaxies colliding. Like snowflakes, no two examples look exactly alike. This is one of the most arresting galaxy smash-up imag...

GRB 041219A
(Preview)
Integral has captured one of the brightest gamma-ray bursts ever seen. A meticulous analysis of the data has allowed astronomers to investigate the initial phases of this giant stellar explosion, which led to the ejection of matter at velocities close to the speed of light. In particular, the astr...

(Preview)
Astronomers using NASA's Swift satellite and Fermi Gamma-ray Space Telescope are seeing frequent blasts from a stellar remnant 30,000 light-years away. The high-energy fireworks arise from a rare type of neutron star known as a soft-gamma-ray repeater. Such objects unpredictably send out a se...
