History was made Wednesday when the European Space Agency successfully landed a spacecraft on a comet for the first time ever.

"We are the first to do this - and that [achievement] will stay forever." said Jean Jacques Dordain, Director General of ESA.

The comet, 67P/Churyumov–Gerasimenko, orbits, the sun every 6.45 years. It is 2.1 miles wide by 2.4 miles long.

Rosetta first launched in 2004 to research the comet, and it didn't arrived at its destination until this past August. On Wednesday morning, Philae first separated from the probe to attempt a landing.

Researchers are hoping to learn more about the origins of the solar system and whether or not comets could have brought water and life to Earth. Watch an ESA animated explanation of Rosetta's journey to the comet and it's surface mission below.

Japanese researchers at Aerial Burton have developed new technology that can project text and images in the sky without using a screen.

According to DigInfo:

"The images are constructed by firing a 1kHz infrared pulse laser into a 3D scanner, which reflects and focuses the pulses of the laser to specific points in the air. The molecules at that point are ionized, and the energy is released as photons."

The company thinks that the device could be used in emergency situations to relay information. Or maybe we can just use it to summon Batman?

How the treatment worked:

1) One of the patient's two olfactory bulbs was removed and the olfactory ensheathing cells (OECs) were grown in culture

2) 100 micro injections of OECs were made above and below the damaged area of the spinal cord

3) Four strips of nerve tissue were placed across an 8mm gap in the spinal cord. The scientists believe the OECs acted as a pathway to stimulate the spinal cord cells to regenerate, using the nerve grafts as a bridge to cross the severed cord

Darek Fidyka, who was paralysed from the chest down in a knife attack in 2010, can now walk using a frame.

The treatment, a world first, was carried out by surgeons in Poland in collaboration with scientists in London.

Details of the research are published in the journal Cell Transplantation.

Love really is timeless.

Via Discovery: The skeletal remains of two lovebirds were uncovered, after being locked in a romantic embrace for the past 700 years.

Archeologists found the happy couple holding hands in an earthen grave during an excavation of a "lost" chapel in Leicestershire, England, researchers reported Thursday (Sept. 18).

"We have seen similar skeletons before from Leicester where a couple has been buried together in a single grave," Vicki Score, University of Leicester Archaeological Services (ULAS) project manager, said in a statement.
