A new video shows the first stage of SpaceX's Falcon 9 rocket crashing and burning after nearly pulling off an unprecedented touchdown on an unmanned "drone ship" in the Atlantic Ocean. The booster stage attempted the landing after successfully launching SpaceX's robotic Dragon capsule toward the International Space Station on a cargo mission for NASA. SpaceX released the video on Wednesday (April 15), one day after the company unveiled a greenier, grainier and shorter version that stopped just when the rocket stage was about to topple over and explode.

Hubble, a joint project of NASA and the European Space Agency (ESA), blasted off aboard the space shuttle Discovery on April 24, 1990. Spacewalking astronauts fixed a serious problem with the telescope's optics in 1993, and Hubble has been transforming astronomers' understanding of the cosmos — and bringing gorgeous images of the universe into laypeople's lives —ever since. "It has really allowed people to participate in the excitement of discovery," said Mario Livio, an astrophysicist based at the Space Telescope Science Institute in Baltimore, which operates Hubble's science program.

(Reuters) - A joint venture of Lockheed Martin Corp and Boeing Co on Wednesday said uncertainty over its use of Russian rocket engines for Air Force satellite launches could undermine its plans to build a new rocket with a U.S. engine. Tory Bruno, president of the United Launch Alliance joint venture, told Reuters that Lockheed and Boeing could halt investment in the new rocket unless ULA gets permission to use 29 already ordered Russian engines for Air Force launches.

Because the condition, known as variant Creutzfeldt-Jakob disease, is so rare, the man was misdiagnosed and even hospitalized for psychiatric symptoms multiple times before doctors suspected the true cause of his symptoms, according to the report from researchers at the Centers for Disease Control and Prevention and Baylor College of Medicine. Variant Creutzfeldt-Jakob disease is thought to arise from eating beef contaminated with infectious prions, which are proteins that fold abnormally and form lesions in the brain. In the United Kingdom, there have been nearly 200 cases of variant Creutzfeldt-Jakob disease tied to eating contaminated beef in the 1980s and 1990s.

There are some likely explanations for why people are crazy about the Apple Watch, which is scheduled to be released on April 24. The conventional view is that it's merely a cool new gadget, said Markus Giesler, a marketing professor at York University in Canada. "When you buy an Apple Watch, you're not just buying this watch — you're also buying the interface into this matrix Apple has created" — a world that consists of other Apple products, such as the iPhone, iPod, MacBook and iPad, he said.

"The octopus, as usual, surprised us," Levy told Live Science. Octopuses use unique strategies to coordinate their arms while crawling, the researchers found.

The spacing between pregnancies can affect the health of the baby, according to the report from researchers at the Centers for Disease Control and Prevention. Overall, about 30 percent of the women had a gap of less than 18 months between pregnancies, according to the report, which looked at data from 2003 to 2011. The pattern in pregnancy spacing seen in the new report was similar to findings from the 2006-2010 National Survey of Family Growth, the researchers said.

In one experiment, dogs were put in a room with their owners. The researchers tracked their interaction and measured oxytocin levels through urine samples.

"These galaxies lived 10 billion years in the past — three billion years after the Big Bang — and are star-forming at high rates, and are the progenitors of the massive dead galaxies of today's universe," lead author Sandro Tacchella, a Ph.D. student at ETH Zurich's institute for astronomy in Switzerland, told Space.com. One leading theory says that a supermassive black hole drives gas out and disrupts star formation, while the other supposes there is a yet-unexplained mechanism that switches off the gas supply in the center. Also interesting was the smaller, elliptical galaxies from this era were still churning out stars throughout their masses.

A Swedish team of scientists has used the Atacama Large Millimeter/submillimeter Array (ALMA) — a huge radio telescope in Chile — to unmask a supermassive black hole's extremely powerful magnetic field. The team, led by Ivan Marti-Vidal from the Onsala Space Observatory and Chalmers University of Technology, was therefore able to peer deep into the heart of the distant galaxy where the black hole lies, and see the region just light-days away from the behemoth. "Our discovery is a giant leap in terms of observing frequency, thanks to the use of ALMA, and in terms of distance to the black hole where the magnetic field has been probed," said co-author Sebastien Muller, also from Onsala Space Observatory and Chalmers University of Technology, in a statement.
