Dead galaxies defy galactic formation theories - space - 01 September 2005

The stagnant behemoths appear to challenge the leading theory that such large objects grew up gradually over time from the merger of smaller objects. Black holes lurking at their centres may be responsible for the arrested development. Astronomers using a 3.5-metre telescope at Kitt Peak National Observatory in Arizona, US, and a 4-metre telescope at Cerro Tololo Inter-American Observatory in La Serena, Chile, made the discovery after studying the spectra of about 4100 "red" galaxies within about a billion light years of the Milky Way. Red galaxies show few new stars, which tend to make galaxies appear blue. The survey found that the largest galaxies had already stopped forming stars about 13 billion years ago, when the Universe was only about 700 million years old.

It's crunch time for dark matter if WIMPs don't show - space - 28 May 2014. If dark matter isn't made of WIMPs, could neutrinos or axions fit the bill?

It's crunch time for dark matter if WIMPs don't show - space - 28 May 2014

What if it's not a particle at all but a strange modification of gravity? ROADS may soon diverge in the dark matter wood, and some physicists want to take the ones less travelled. The most promising candidate for a dark matter particle could be about to show itself at last, as it is running out of places to hide. But should the hunters fail to bag one of these WIMPs, or weakly interacting massive particles, the search for dark matter could be thrown into crisis.

Space's 10 Most Gigantic Objects. Newborn Star's 'Snow Line' Reveals Clues About Planet Formation. Astronomers have identified the point where carbon monoxide (CO) freezes in the disk around a sunlike star — information that could help them understand how planets form.

Newborn Star's 'Snow Line' Reveals Clues About Planet Formation

A team of international scientists has calculated the CO "snow line" for a star called TW Hydrae, determining that the gas solidifies at about the distance of the orbit of Neptune, where it could help feed the formation of the outer edges of the system. "The CO snow line is interesting, not only because CO is abundant in the disks, but its snow line is the most accessible to direct observations due to its low freeze-out temperature — it's farther away from the star," said principal investigator Chunhua Qi of the Harvard-Smithsonian Center for Astrophysics. "It could mark the starting point where smaller icy bodies, like comets, and dwarf planets, like Pluto, would begin to form.

Lost Opportunity. NASA Funds 12 Far-Out Space Tech Ideas. NASA has granted funding to a dozen imaginative tech concepts, in the hopes that one or more of them will lead to big breakthroughs in space science and exploration.

NASA Funds 12 Far-Out Space Tech Ideas

The 12 ideas, which were selected under Phase 1 of the NASA Innovative Advanced Concepts (NIAC) program, are ambitious and varied. One aims to build biomaterials such as human tissue with a 3D printer, for example, while another proposes to induce deep-sleep torpor states in astronauts making the long journey to Mars. "These new Phase 1 selections include potential breakthroughs for Earth and space science, diverse operations and the potential for new paths that expand human civilization and commerce into space," NIAC program executive Jay Falker said in a statement. [Future Visions of Human Spaceflight] Phase 1 awards are worth about $100,000. The 12 selected concepts, along with their principal investigators, are: — Pulsed Fission-Fusion (PuFF) Propulsion System (Rob Adams, NASA Marshall Space Flight Center) Astronomy Pronunciation Guide.

But what you might not know is that, when it thinks nobody is looking, space puts on a frilly dress, covers its forearms in honey and spins around until it falls over ... because space is just flat-out crazy as hell.

The 6 Most Mind-Blowing Things Ever Discovered in Space

The planets in our own solar system all seem to be empty rocks or balls of gas, and you find a whole lot of nothing before you get to the next star. Meanwhile, Hollywood's most creative minds can't get past populating the place with planets that look a whole lot like Earth (and specifically, parts of California) featuring monsters, rapey aliens or Muppets. But real space is far, far stranger. You just have to know where to look to find things like ... #6. Scientists Now Know: We're From Sagittarius Dwarf Galaxy!

Summary & comments by Dan Eden for Viewzone "This first full-sky map of Sagittarius shows its extensive interaction with the Milky Way," Majewski said. "Both stars and star clusters now in the outer parts of the Milky Way have been 'stolen' from Sagittarius as the gravitational forces of the Milky Way nibbled away at its dwarf companion.
