CLASP-2: Investigating the magnetic solar chromosphere

Four years ago, an international team (USA, Japan and Europe) carried out an unprecedented suborbital space experiment called CLASP-1, motivated by theoretical investigations carried out at the IAC by Javier Trujillo Bueno ...

UVB radiation influences behavior of sticklebacks

Fish cannot see ultraviolet B rays, but still change their behavior when they grow up under increased UVB intensity. According to studies by biologists at the University of Bonn on three-spined sticklebacks (Gasterosteus ...

Nasa tests life-detection drill in Earth's driest place

(Phys.org) —Watching starbirth isn't easy: tens of millions of years are needed to form a star like our Sun. Much like archeologists who reconstruct ancient cities from shards of debris strewn over time, astronomers must ...

The wings of the Seagull Nebula

(Phys.org)—This new image from ESO shows a section of a cloud of dust and glowing gas called the Seagull Nebula. These wispy red clouds form part of the "wings" of the celestial bird and this picture reveals an intriguing ...

The Helix nebula: Bigger in death than life

(Phys.org)—A dying star is refusing to go quietly into the night, as seen in this combined infrared and ultraviolet view from NASA's Spitzer Space Telescope and the Galaxy Evolution Explorer (GALEX), which NASA has lent ...
