Observing the image of a faint object that lies close to a star is a demanding task as the object is generally hidden in the glare of the star. Characterising this object, by taking spectra, is an even harder challenge. Still, thanks to ingenious scientists and a new ESO imaging spectrograph, this is now feasible, paving the way to an eldorado of many new thrilling discoveries.

A new image from NASA's Spitzer Space Telescope shows infant stars "hatching" in the head of Orion, the famous hunter constellation visible from northern hemispheres during winter nights.

A study of brown dwarfs has revealed that these "failed stars" can possess powerful magnetic fields and emit lighthouse beams of radio waves thousands of times brighter than any detected from the Sun. The brown dwarfs are behaving like pulsars, one of the most exotic types of object in our Universe.

A recent study found 20 new star systems in the sun’s local neighborhood. Most of the new discoveries are red dwarfs, much smaller and dimmer than the sun. Yet scientists are growing more confident that these stars could host habitable planets.

In one of the most detailed astronomical images ever produced, NASA's Hubble Space Telescope captured an unprecedented look at the Orion Nebula. This turbulent star formation region is one of astronomy's most dramatic and photogenic celestial objects.

New Spitzer Space Telescope observations of an unusual class of interacting binary stars detected excess amounts of infrared radiation, suggesting that these odd objects are surrounded by large disks of cool dust.

Brown dwarfs, like more massive normal stars, are formed when interstellar gas and dust clouds collapse. When this happens, a central, dense area builds up, embedded in a rotating disc made of gas and dust. These circumstellar discs produce infrared radiation according to their temperature.

NASA's Spitzer Space Telescope has spotted the very beginnings of what might become planets around the puniest of celestial orbs -- brown dwarfs, or "failed stars." The telescope's infrared eyes have for the first time detected clumps of microscopic dust grains and tiny crystals orbiting five brown dwarfs.
