Rosetta's mission came to an end

Rosetta - a mission from the ESA - followed a comet called 67P through Space for a long time. Rosetta got a lot of information, such as temperature measurements, photos, dust grains, measurements of the gravity and the magnetic field of the comet and so on. However, the most remarkable discovery is that she found ingredients that were crucial for the origin of life on Earth.

Rosetta's mission is considered a huge success because it was the first attempt in history to send a lander to a comet.

Gravitational waves have been detected

Researchers from Harvard-Smithsonian Center for Astrophysics, using a telescope located at the South Pole, have detected gravitational waves. If the results are confirmed, this discovery could be a signal from the beginning of time.

These waves, according to inflation theory, are images of the hypothetical particles gravitons that transmit gravity in quantum theory.

OLDEST, MOST DISTANT GALAXY FOUND

Astronomers find the oldest galaxy . It appears near the Great Bear constellation. The name of this new galaxy is so difficult for us: z8_GND_5296. It was discovered by Steven Finkelstein and his colleagues. This new galaxy makes new stars more than 100 times faster than our galaxy does, the Milky Way.

Comet ISON

A chunk of frozen rock and ice about the size of a mountain is moving toward the sun. Some Russian astronomers discovered the comet called ISON on Sept. 21, 2012. By Nov. 5, they estimated it was racing toward the sun at nearly 45 kilometers per second.The comet accelerates as it approaches the sun. Astronomers predict the comet will reach its closet point to the sun by the end of November.
