MIT researchers devise see-through-wall technology

Through the use of microwaves, MIT researchers have devised technology to see through walls in real time.

The radar array system, created by Gregory Charvat and John Peabody at the university's Lincoln Laboratory, sends microwave signals that bounce off objects and ultimately return radar images to a screen. The waves can even penetrate concrete walls.

Charvat said Tuesday that the project has been in the works for a while.

“It originally started out as my dissertation, where I developed a very slow prototype,” he said. “When I moved to Lincoln Lab, I teamed up with another colleague (Peabody) who was working with technology used for imaging human tissue” in medical environments such as hospitals.

Study shows unprecedented loss of ozone above Arctic

Loss of the Earth’s ozone layer above the Arctic last winter was unprecedented, scientists at NASA’s Jet Propulsion Laboratory told CNN on Monday.

In findings published in a new study in the journal Nature, scientists said a hole in the ozone was caused by an unusually long period of low temperatures in the stratosphere, the protective layer that shields the Earth’s surface from harmful radiation.

While ozone loss is a sadly common occurrence at the South Pole, recent findings document a similar event happening at the Earth’s northernmost point. “We’ve never seen that kind of phenomenon in the Arctic before,” Michelle Santee, an atmospheric scientist with the Jet Propulsion Laboratory, said.

Although it was comparatively small – “The area of the Arctic loss zone was about 60% the size of a typical ozone hole,” Santee said – the ozone hole has raised concerns among atmospheric scientists.

“The same process that destroys the ozone layer in Antarctica – chlorine and other man-made compounds such as CFCs (chlorofluorocarbons) – takes place here also, but it’s just that it never occurred in the Arctic to the same degree,” Santee said.

Awesome telescope sheds new light on cosmos

From a mountaintop in northern Chile, the largest visible-light telescope in the world has captured stunning images of the cosmos in never-before-seen detail.

The Paranal Observatory released initial images Wednesday from the powerful VLT Survey Telescope.

The images constitute a celestial breakthrough for the 15-nation European Southern Observatory, which runs the Paranal Observatory and has worked with astronomers to build telescopes that survey the sky in large segments.

NASA shows first pics of shuttle docked to space station

Newly released pictures from NASA are the first that show a shuttle docked to the International Space Station.

The decidedly risky photo session, which shows space shuttle Endeavour docking in its final days in orbit, was performed by Soyuz TMZ-20 crewmember Paolo Nespoli, who counts photography as a hobby, according to his NASA bio.

The photos were taken two weeks ago from the vantage point of the Soyuz, a manned spaceflight combining the resources of the European Space Agency, NASA and its Russian counterpart, Roscosmos.

In addition to Nespoli, aboard the Soyuz were members of Expedition 27, Russian cosmonaut Dmitry Kondratyev and NASA astronaut Cady Coleman, who made news last month when she sent an email from space for Mother's Day.
