The most distant object yet discovered in the Universe
ESO's Very Large Telescope has shown that a faint gamma-ray burst detected on the 23 of April 2009, is the signature of the explosion of the earliest, most distant known object in the Universe (a redshift of 8.2). The explosion apparently took place more than 13 billion years ago, only about 600 million years after the Big Bang.

Lightest exoplanet yet discovered
A team of astronomers, which includes Nuno Santos from Centro de Astrofísica da Universidade do Porto (CAUP), announced today the discovery of the smallest exoplanet yet discovered.

A new era in the study of stars
Initial results obtained by CoRot study on the seismic activity of three solar-type stars show that they are a little warmer and bigger than our Sun. The celestial bodies have an activity on the surface, granulation, three times higher than that of the Sun and, with the time-scale is three times higher.
These test results allow predictions of several theoretical models that are important for understanding the phenomenon of oscillations in stars and their activity.

Stellar Firework in a Whirlwind
Most of the stars in the known Universe are not alone. They usually live in binary systems. But sometimes, when one of the stars is a white dwarf, it gets too greedy and starts devouring its partner, exploding as a Supernova. This was observed in the galáxy NGC 1288.

The topsy-turvy Galaxie
The captivating appearance of this image of the starburst galaxy NGC 1313, taken with the FORS instrument at ESO's Very Large Telescope, belies its inner turmoil. The dense clustering of bright stars and gas in its arms, a sign of an ongoing boom of star births, shows a mere glimpse of the rough times it has seen.

Cut from different cloth
After determining the chemical composition of over 2000 stars in four of the nearest dwarf galaxies to our own, astronomers have demonstrated fundamental differences in their make-up, casting doubt on the theory that these diminutive galaxies could ever have formed the building blocks of our Milky Way Galaxy.
13 November 2006
Stellar vampires unmasked
Astronomers have found possible proofs of stellar vampirism in the globular cluster 47 Tucanae. Using ESO's Very Large Telescope, they found that some hot, bright, and apparently young stars in the cluster present less carbon and oxygen than the majority of their sisters. This indicates that these few stars likely formed by taking their material from another star.

The star, the dwarf and the planet
Astronomers have detected a new faint companion to the star HD 3651, already known to host a planet. This companion, a brown dwarf, is the faintest known companion of an exoplanet host star imaged directly and one of the faintest T dwarfs detected in the Solar neighbourhood so far.

Backward Sunspot
On July 31st, a tiny sunspot was born. It popped up from the sun's interior, floated around a bit, and vanished again in a few hours. On the sun this sort of thing happens all the time and, ordinarily, it wouldn't be worth mentioning. But this sunspot was special: It was backward.

A Sub-Stellar Jonah
Using ESO's Very Large Telescope, astronomers have discovered a rather unusual system, in which two planet-size stars, of different colours, orbit each other. One is a rather hot white dwarf, weighing a little bit less than half as much as the Sun. The other is a much cooler, 55 Jupiter-masses brown dwarf.

Falling onto the dark
ESO's VLT has helped scientists to discover a large primordial 'blob', more than 10 billion light-years away. The most likely scenario to account for its existence and properties is that it represents the early stage in the formation of a galaxy, when gas falls onto a large clump of dark matter.

Life is not easy, even for galaxies. Some indeed get so close to their neighbours that they get rather distorted. But such encounters between galaxies have another effect: they spawn new generations of stars, some of which explode.

Trio of Neptunes and their Belt
Using the ultra-precise HARPS spectrograph on ESO's 3.6-m telescope at La Silla (Chile), a team of European astronomers have discovered that a nearby star is host to three Neptune-mass planets. The innermost planet is most probably rocky, while the outermost is the first known Neptune-mass planet to reside in the habitable zone. This unique system is likely further enriched by an asteroid belt.

Twin explosions in gigantic dusty potato crisp
ESO's Very Large Telescope, equipped with the multi-mode FORS instrument, took an image of NGC 3190, a galaxy so distorted that astronomers gave it two names. And as if to prove them right, in 2002 it fired off, almost simultaneously, two stellar explosions, a very rare event.

Physics in Universe's Youth
Using a quasar located 12.3 billion light-years away as a beacon, a team of astronomers detected the presence of molecular hydrogen in the farthest system ever, an otherwise invisible galaxy that we observe when the Universe was less than 1.5 billion years old, that is, about 10% of its present age.

The Cosmic Dance of Distant Galaxies
Studying several tens of distant galaxies, an international team of astronomers found that galaxies had the same amount of dark matter relative to stars 6 billion years ago as they have now. If confirmed, this suggests a much closer interplay between dark and normal matter than previously believed. The scientists also found that as many as 4 out of 10 galaxies are out of balance. These results shed a new light on how galaxies form and evolve since the Universe was only half its current age.

A blast to chase
Possibly similar to what our own Milky Way looks like, Messier 100 is a grand design spiral galaxy that presents an intricate structure.

There's more to the North Star than meets the eye
We tend to think of the North Star, Polaris, as a steady, solitary point of light that guided sailors in ages past. But there is more to the North Star than meets the eye. The North Star is actually a triple star system. And while one companion can be seen easily through small telescopes, the other hugs Polaris so tightly that it has never been seen until now.

It's Far, It'a Small, It'a Cool
Using a network of telescopes scattered across the globe, including the Danish 1.54m telescope at ESO La Silla (Chile), astronomers discovered a new extrasolar planet significantly more Earth-like than any other planet found so far. The planet, which is only about 5 times as massive as Earth, circles its parent star in about 10 years.
