European Extremely Large Telescope gets final go-ahead

The ESO has given its European Extremely Large Telescope (E-ELT) the final green light, allowing construction to go ahead at the Chilean site. The telescope is expected to take around a decade to complete, with the final installation expected to facilitate discoveries in fields such as galaxy composition and exoplanets. Read More

Detection of super-Earth transit puts ground-based telescopes in the hunt

When you're hunting for exoplanets many light years away, the complications posed by the Earth's atmosphere can make the search incredibly difficult for ground-based telescopes. That's why space-based telescopes, such as Hubble, Spitzer and Kepler, are generally employed for the job. But now for the first time, astronomers have detected the transit of a super-Earth in front of a nearby Sun-like star, which could see ground-based telescopes more widely used in categorizing the growing number of exoplanets expected to be discovered in the next few years.Read More

Smart dust could put telescopes in a spray can

Good things come in small packages – and sometimes in aerosol cans. To prove this, researchers at the Rochester Institute of Technology (RIT) and NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California are working on technology for a future generation of space telescopes that may one day see the giant instruments replaced by swarms of particles that are deployed from a can and herded into place by laser beams.Read More

Discovery of new molecule suggests origins of life may reside in interstellar space

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) group of radio telescopes have discovered a carbon-based molecule with a branched structure – a common feature in molecules that are required for life to form. Contained within a giant gas cloud in the star-forming region of Sagittarius B2, the molecule of isopropyl cyanide is the first hint that other complex molecules may form in space before finding their way to the surface of planets.

Dwarf galaxy suggests black holes may be more common than previously thought

Astronomers from the University of Utah, using the Gemini North telescope on Hawaii’s Mauna Kea and images captured by the Hubble Space Telescope, have discovered a dwarf galaxy that is the smallest ever recorded with a supermassive black hole at its center. The galaxy, M60-UCD1, has been found to contain a black hole with a mass equivalent to 21 million times that of our own sun and whose presence may suggest that such enormous black holes could be more common than previously thought.Read More

Hubble helps find hidden supernova companion

A star accompanying a rare type of supernova in close orbit has been discovered by astronomers using NASA's Hubble Space Telescope. Confirming a long-held theory that the explosion originated in a binary star arrangement, observations verify that the companion star precipitated the destruction of the aging primary star by drawing off mass until its core collapsed and triggered a supernova event.Read More

Galactic supercluster identified as home to our Milky Way

A new study has revealed that our Milky Way is a member of a group of local galaxies interconnected within a larger supercluster made up of a myriad of other galaxies, all interlinked within a tenuous web of filaments many millions of light years long. Dubbed "Laniakea" (Hawaiian for "immense sky") by astronomers working at the National Science Foundation’s (NSF's) Green Bank Telescope (GBT) and others around the world, this research defines hitherto unknown boundaries and connections in our corner of the universe.Read More

Titanic eruptions on Io could lead to better understanding of Earth's surface formation

A series of three massive volcanic eruptions detected on the surface of Jupiter's moon Io in August last year, has the potential to yield insights into the formation process of the surface of Earth-like planets. By any standards, these eruptions were enormous, characterized as titanic curtains of lava issuing forth from fissures several miles in length, that spewed massive amounts of material high above the moon's surface.Read More

Detecting industrial pollution could be an effective approach to finding ET

According to researchers at the Harvard-Smithsonian Center for Astrophysics (CfA), we might soon be able to detect hints of technologically advanced alien civilizations by measuring high levels of polluting gases in the atmospheres of distant exoplanets. The approach should become viable soon after the James Webb Space Telescope (JWST) is launched in late 2018.Read More
