Das neue Instrument SPHERE zeigt sein Können

Bislang gingen Astronomen davon aus, dass ein Brauner Zwerg den ungewöhnlichen Doppelstern V471 Tauri begleitet. Das neue Instrument SPHERE am Very Large Telescope der ESO hat ihnen den nun bisher besten Blick auf die Umgebung dieses faszinierenden Objekts geliefert und sie fanden — nichts. Das überraschende Fehlen dieses mit großer Sicherheit vorhergesagten Braunen Zwerges bedeutet, dass die herkömmliche Erklärung für das merkwürdige Verhalten von V471 Tauri falsch sein muss. Das unerwartete Ergebnis wird in der ersten Veröffentlichung überhaupt beschrieben, die auf Beobachtungen von SPHERE beruht. (more…)

Das Maul der Bestie: VLT bildet kometenartige Globule CG4 ab

Ähnlich dem gähnenden Schlund einer riesigen himmlischen Kreatur leuchtet die kometenartige Globule CG4 bedrohlich in diesem neuen Bild des Very Large Telescopes der ESO. Obwohl es auf der Aufnahme so scheint, als sei sie groß und hell, handelt es sich bei CG4 tatsächlich nur um einen lichtschwachen Nebel, weshalb es sich für Astronomen als schwierig gestaltet, ihn ausfindig zu machen. Die genaue Beschaffenheit von CG4 bleibt auch weiterhin ein Rätsel. (more…)

PASADENA, Calif. — The spectacular barred spiral galaxy NGC 6872 has ranked among the biggest stellar systems for decades. Now a team of astronomers from the United States, Chile and Brazil has crowned it the largest known spiral, based on archival data from NASA’s Galaxy Evolution Explorer (GALEX) mission, which has since been loaned to the California Institute of Technology in Pasadena.

Measuring tip-to-tip across its two outsized spiral arms, NGC 6872 spans more than 522,000 light-years, making it more than five times the size of our Milky Way galaxy. (more…)

Gaseous Ring Around Young Star Raises Questions

ANN ARBOR, Mich.— Astronomers have detected a mysterious ring of carbon monoxide gas around the young star V1052 Cen, which is about 700 light years away in the southern constellation Centaurus.

The ring is part of the star’s planet-forming disk, and it’s as far from V1052 Cen as Earth is from the sun. Discovered with the European Southern Observatory’s Very Large Telescope, its edges are uniquely crisp. (more…)

*One youngster only six times heftier than Jupiter*

TORONTO, ON – A University of Toronto-led team of astronomers has discovered over two dozen new free-floating brown dwarfs, including a lightweight youngster only about six times heftier than Jupiter, that reside in two young star clusters. What’s more, one cluster contains a surprising surplus of them, harbouring half as many of these astronomical oddballs as normal stars.

“Our findings suggest once again that objects not much bigger than Jupiter could form the same way as stars do. In other words, nature appears to have more than one trick up its sleeve for producing planetary mass objects,” says Professor Ray Jayawardhana, Canada Research Chair in Observational Astrophysics at the University of Toronto and leader of the international team that made the discovery.
