Una estrella de neutrones aislada en la Pequeña Nube de Magallanes

Esta fotografía, creada a partir de imágenes de telescopios tanto terrestres como espaciales, cuenta la historia de la persecución de un escurridizo objeto, difícil de encontrar, y oculto en medio de una compleja maraña de filamentos gaseosos en una de nuestras galaxias vecinas más cercana, laPequeña Nube de Magallanes. La imagen rojiza de fondo proviene […]

This new picture created from images from telescopes on the ground and in space tells the story of the hunt for an elusive missing object hidden amid a complex tangle of gaseous filaments in one of our nearest neighbouring galaxies, the Small Magellanic Cloud. The reddish background image comes from the NASA/ESA Hubble Space Telescope and reveals the wisps of gas forming the supernova remnant 1E 0102.2-7219 in green. The red ring with a dark centre is from the MUSE instrument on ESO’s Very Large Telescope and the blue and purple images are from the NASA Chandra X-Ray Observatory. The blue spot at the centre of the red ring is an isolated neutron star with a weak magnetic field, the first identified outside the Milky Way.

Cuando las luces colisionan

Esta imagen de la semana capta los cielos del Observatorio Paranal de ESO ardiendo en colores: azules, púrpuras, naranjas, verdes, amarillos y rojos se mezclan para crear esta impresionante vista de la ubicación chilena. En primer plano puede verse uno de los telescopios auxiliares (AT) que comprende el Very Large Telescope (VLT) de ESO, bañado […]

This Picture of the Week captures the skies above ESO’s Paranal Observatory ablaze with colour — blues, purples, oranges, greens, yellows and reds all mingle together to create this striking view of the Chilean site. One of the Auxiliary Telescopes (ATs) comprising ESO’s Very Large Telescope (VLT) is visible in the foreground, bathed in an eerie yellow-green glow.  This AT is just one of the VLT’s four 1.8-metre auxiliaries, which also includes four giant 8.2-metre cousins (Unit Telescopes).The ATs are unique; they are self-contained and, depending on the needs of the observing project, can be repositioned in up to 30 different observing locations along a system of tracks. Acting together as the VLT Interferometer (VLTI), they capture light from celestial objects and send it to the same focal point through a system of mirrors housed within underground tunnels, allowing researchers to observe the cosmos in incredible detail.  Comprising eight telescopes in total, the VLT is the world’s most advanced visible-light astronomical observatory. Its magnificent resolution makes it possible to see fine detail on the surface of a star, and even to study the surroundings of a black hole.

Imagen obtenida con el VLT del glóbulo cometario CG4

  Como las fauces abiertas de una gigantesca criatura celeste, el glóbulo cometario CG4 refulge amenazante en esta nueva imagen del VLT (Very Large Telescope) de ESO. Aunque en la fotografía parece grande y brillante, en  realidad se trata de una nebulosa débil, difícil de observar. La naturaleza exacta de CG4 sigue siendo un misterio. […]

Like the gaping mouth of a gigantic celestial creature, the cometary globule CG4 glows menacingly in this image from ESO’s Very Large Telescope. Although it looks huge and bright in this image it is actually a faint nebula and not easy to observe. The exact nature of CG4 remains a mystery.

We’ve found six scorchingly hot exoplanets that are over 1100°C

We have discovered six new exoplanets by looking at hot gas nearby. Carole Haswell at the Open University in the UK and her colleagues made the discovery by studying nearby stars that the exoplanets orbit. The six exoplanets are all extremely hot, with temperatures of between 1100°C and 1800°C. They range in mass from around […]

Starry reflections on the Swedish–ESO Submillimetre Telescope

he starry skies are reflected in one of the many telescopes hosted at La Silla, ESO’s first observatory. The Milky Way can be seen as a bright band crossing the top right corner. This picture demonstrates one of the clear skies that astronomers here enjoy on more than 300 nights per year. As the home […]

The starry skies are reflected in one of the many telescopes hosted at La Silla, ESO's first observatory. The Milky Way can be seen as a bright band crossing the top right corner. This picture demonstrates one of the clear skies that astronomers here enjoy on more than 300 nights per year. As the home of such advanced instruments as the New Technology Telescope (NTT) and the High Accuracy Radial velocity Planet Searcher (HARPS), La Silla remains among the most scientifically productive observatories in the world.
