Astronomers using NASA’s Hubble Space Telescope have unexpectedly discovered the most distant cosmic magnifying glass, produced by a monster elliptical galaxy. Seen here as it looked 9.6 billion years ago, this monster elliptical galaxy breaks the previous record holder by 200 million years. These “lensing” galaxies are so massive that their gravity bends, magnifies, and distorts light from objects behind them, a phenomenon called gravitational lensing.

The object behind the cosmic lens is a tiny spiral galaxy undergoing a rapid burst of star formation. Its light has taken 10.7 billion years to arrive here. Seeing this chance alignment at such a great distance from Earth is a rare find.

Locating more of these distant lensing galaxies will offer insight into how young galaxies in the early universe built themselves up into the massive dark-matter-dominated galaxies of today. Dark matter cannot be seen, but it accounts for the bulk of the universe’s matter.

“When you look more than 9 billion years ago in the early universe, you don’t expect to find this type of galaxy-galaxy lensing at all,” explained lead researcher Kim-Vy Tran of Texas A&M University in College Station. “It’s very difficult to see an alignment between two galaxies in the early universe.”

NASA TV News Conference To Discuss Planck Cosmology Findings

NASA will host a news conference at 8 a.m. PDT (11 a.m. EDT) Thursday, March 21, to discuss the first cosmology results from Planck, a European Space Agency mission with significant NASA participation.

The briefing will be held at NASA Headquarters in Washington. It will be broadcast live on NASA Television and streamed on the agency’s website.

Planck launched into space in 2009 and has been scanning the skies ever since, mapping cosmic microwave background, or the afterglow, of the big bang that created our universe more than 13 billion years ago.

New Radio Telescope Could Save World Billions

December 2, 2012 Leave a comment

A small pocket of Western Australia’s remote outback is set to become the eye on the sky and could potentially save the world billions of dollars. The Murchison Widefield Array (MWA) radio telescope, unveiled today, Friday 30 November, will give the world a dramatically improved view of the Sun and provide early warning to prevent damage to communication satellites, electric power grids and GPS navigation systems.

The $51 million low-frequency radio telescope will be able to detect and monitor massive solar storms, such as the one that cut power to six million people in Canada in 1989 during the last peak in solar activity. In 2011, experts warned that a major solar storm could result in damage to integral power supplies and communication networks of up to US$2 trillion – the equivalent of a global Hurricane Katrina.

The MWA will aim to identify the trajectory of solar storms, quadrupling the warning period currently provided by near-Earth satellites. This is timely as the Sun is due to re-enter peak activity in 2013, with a dramatic increase in the number and severity of solar storms expected, with the potential to disrupt global communications and ground commercial airlines.

NASA Hosts Sept. 19 Teleconference About Mars Curiosity Rover Progress

September 18, 2012 1 comment

NASA will host a media teleconference at 11 a.m. PDT (2 p.m. EDT) on Wednesday, Sept. 19, to provide a status update on the Curiosity rover’s mission to Mars’ Gale Crater.

Curiosity, the Mars Science Laboratory, is 43 days into a two-year mission to investigate whether conditions may have been favorable for microbial life.

SLOOH Space Camera To Track Newly Discovered Potentially Hazardous Asteroid 2012 QG42 On Its Close Approach To Earth

September 12, 2012 Leave a comment

Discovered by the Catalina Sky Survey in Arizona on August 26, 2012, PHA (potentially hazardous asteroid) 2012 QG42, an asteroid the size of a 14-story building, will make its close approach to Earth Thursday evening (September 13) — just months after newly discovered asteroid 2012 LZ1 paid an unexpected visit to Earth on June 16th. Slooh Space Camera will cover its near-approach on Sept. 13, live on Slooh.com, free to the public, starting at 4:00 p.m. PDT / 7:00 p.m. EDT / 23:00 UTC — accompanied by real-time discussions with Slooh President Patrick Paolucci, Slooh Engineer Paul Cox, and Astronomy Magazine columnist Bob Berman. Viewers can watch live on their PC or favorite iOS/Android mobile device.

The asteroid is estimated to be 190-430 meters (625-1,400 ft) across and will pass within 7.5 times the Moon’s distance from our planet.

Due to its proximity to Earth and size, 2012 QG42 qualifies as a “potentially hazardous asteroid”, which means that it could collide with Earth in the distant future.

JPL To Stream Mars Curiosity Telecon And Lecture

September 12, 2012 Leave a comment

NASA will host a media teleconference at 11 a.m. PDT (2 p.m. EDT) tomorrow (Wednesday, Sept. 12), to provide a status update on the Curiosity rover’s mission to Mars’ Gale Crater.

The Mars Science Laboratory spacecraft is more than one month into a two-year mission to investigate whether conditions have been favorable for microbial life and preserving clues in the rocks about possible past life.

Also this week, Mars Science Laboratory Project Manager Richard Cook will speak Thursday, Sept. 13 in JPL’s von Karman Auditorium. The lecture, which begins at 7 p.m. PDT (10 p.m. EDT), is open to the public and will be broadcast live with moderated chat, on JPL’s Ustream channel.

To Planets And Beyond: Voyager Celebrates 35 Years

September 5, 2012 Leave a comment

NASA’s Jet Propulsion Laboratory celebrates the 35-anniversary of the Voyager mission, whose twin spacecraft conducted a Grand Tour of the planets and are now headed into interstellar space. A panel discussion in JPL’s von Karman auditorium will highlight insider stories about designing the planetary tour, Voyager’s post-launch “anxiety attack,” Voyager 2’s encounter with Neptune, and the Golden Record.
