ALMA and VLT probe surprisingly dusty and evolved galaxy.
One of the most distant galaxies ever observed has provided astronomers with the first detection of dust in such a remote star-forming system and tantalising evidence for the rapid evolution of galaxies after the Big Bang. The new observations have used ALMA to pick up the faint glow from cold dust in the galaxy A1689-zD1 and used ESO’s Very Large Telescope to measure its distance.
“Although the exact origin of galactic dust r [...]
On March 1, 2015, SpaceX’s Falcon 9 rocket delivered the ABS 3A and EUTELSAT 115 West B all-electric satellites to a supersynchronous transfer orbit. Marking Falcon 9’s sixteenth launch and the vehicle’s most voluminous payload to date, the liftoff occurred at 10:50pm EST from SpaceX’s Launch Complex 40 at Cape Canaveral Air Force Station, Fla.
The rocket and payload went vertical on the launch pad on Saturday, February 28. Liftoff occurred at the front of the launch window, with Fal [...]
The Space Show, hosted by David Livingston at www.TheSpaceShow.com, will have the following guests this week:
1. Monday, March 2, 2015, 2-3:30 PM PST (22-23:30 GMT)
DR. JAMES DEWAR returns to discuss nuclear propulsion. This program will be co-hosted with DR. JOHN JURIST.
James A. Dewar worked exclusively on nuclear policy issues in the Atomic Energy Commission and its successor agencies, the Energy Research and Development Administration and the Department of Energy. Such included non [...]
It is not every day that such an interesting cloud photobombs your image. The original plan was to photograph a rare angular conjunction of Mars and Venus that occurred a week and a half ago, with the added bonus of a crescent Moon and the International Space Station (ISS) both passing nearby. Unfortunately, on Madeira Island, Portugal, this event was clouded out. During the next day, however, a spectacular lenticular cloud appeared before sunset, so the industrious astrophotographer quickly for [...]
NASA astronauts Terry Virts and Barry Wilmore ended their spacewalk at 12:30 p.m. EST with the repressurization of the Quest airlock. Virts and Wilmore completed installing 400 feet of cable and several antennas associated with the Common Communications for Visiting Vehicles system known as C2V2. Boeing’s Crew Transportation System (CST)-100 and the SpaceX Crew Dragon will use the system in the coming years to rendezvous with the orbital laboratory and deliver crews to the space station. They [...]
Almost every object in the above photograph is a galaxy. The Coma Cluster of Galaxies pictured above is one of the densest clusters known - it contains thousands of galaxies. Each of these galaxies houses billions of stars - just as our own Milky Way Galaxy does. Although nearby when compared to most other clusters, light from the Coma Cluster still takes hundreds of millions of years to reach us.
In fact, the Coma Cluster is so big it takes light millions of years just to go from one side t [...]
Astronomers using data from NASA's Wide-field Infrared Survey Explorer, or WISE, have found a cluster of stars forming at the very edge of our Milky Way galaxy.
"A stellar nursery in what seems to be the middle of nowhere is quite surprising," said Peter Eisenhardt, the project scientist for the WISE mission at NASA's Jet Propulsion Laboratory in Pasadena, California. "But surprises turn up when you look everywhere, as the WISE survey did."
The discovery, led by Denilso Camargo of the [...]
Taken on February 20, five different exposures made in rapid succession were used to created this tantalizing telephoto image. In combination, they reveal a wide range of brightness visible to the eye on that frigid evening, from the urban glow of the Quebec City skyline to the triple conjunction of Moon, Venus and Mars.
Shortly after sunset the young Moon shows off its bright crescent next to brilliant Venus. Fainter Mars is near the top of the frame. Though details in the Moon's sunlit cre [...]
International Space Station managers met Friday morning and gave approval to proceed with U.S. EVA 31 on Sunday, March 1 as planned. The Mission Management Team reviewed the status of spacewalk preparations as well as an analysis of the minor seepage of water into the helmet of Expedition 42 Flight Engineer Terry Virts of NASA following the last spacewalk on Feb. 25 after he was back in the crew lock section of the Quest airlock and the repressurization of the airlock had begun.
Spacewalk spe [...]
An article published in Science confirms the existence of methane fluctuations in the atmosphere of Mars, as a result of the detailed analysis of data sent during 605 soles or Martian days
The tunable laser spectrometer in the SAM (Sample Analysis at Mars) instrument of the Curiosity robot has unequivocally detected an episodic increase in the concentration of methane in Mars' atmosphere after an exhaustive analysis of data obtained during 605 soles or Martian days.
This has been revealed [...]
The galaxy pictured here is NGC 4424, located in the constellation of Virgo. It is not visible with the naked eye but has been captured here with the NASA/ESA Hubble Space Telescope.
Although it may not be obvious from this image, NGC 4424 is in fact a spiral galaxy. In this image it is seen more or less edge on, but from above, you would be able to see the arms of the galaxy wrapping around its center to give the characteristic spiral form.
In 2012, astronomers observed a supernova in [...]
