Oxygen Increased When Earth Was Covered in Ice - Astrobiology Magazine
http://www.astrobio.net/also-in-news/oxygen-increased-earth-covered-ice/

In the beginning, planet Earth was a very inhospitable place with no oxygen and only single-celled bacteria as inhabitants. According to a new study,
the oxygen content in the air began to increase about 2.4 billion years ago, at the same time as the global glaciation and when all continents were gathered
in a single huge landmass, or supercontinent. How to explain the exact connection between these events, however, is a question that baffles the researchers.

“Our results also show that oxidation coincided in time with an event of global glaciation of the Earth and extensive volcanism”, says Ulf Söderlund,
Professor of Geology at the Faculty of Science at Lund University in Sweden.

In the recent international study, researchers from Lund University, among others, have pinpointed the timing of this so-called Great Oxidation Event —
a crucial starting point in the development of life.

News | Asteroid Resembles Dungeons and Dragons Dice

Radar images of asteroid 2017 BQ6 were obtained on Feb. 6 and 7 with NASA's 70-meter (230-foot) antenna at the Goldstone Deep Space Communications
Complex in California. They reveal an irregular, angular-appearing asteroid about 660 feet (200 meters) in size that rotates about once every three
hours. The images have resolutions as fine as 12 feet (3.75 meters) per pixel.

"The radar images show relatively sharp corners, flat regions, concavities, and small bright spots that may be boulders," said Lance Benner of NASA's
Jet Propulsion Laboratory in Pasadena, California, who leads the agency's asteroid radar research program. "Asteroid 2017 BQ6 reminds me of the dice
used when playing Dungeons and Dragons. It is certainly more angular than most near-Earth asteroids imaged by radar."

Asteroid 2017 BQ6 safely passed Earth on Feb. 6 at 10:36 p.m. PST (1:36 a.m. EST, Feb. 7) at about 6.6 times the distance between Earth and the moon
(about 1.6 million miles, or 2.5 million kilometers). It was discovered on Jan. 26 by the NASA-funded Lincoln Near Earth Asteroid Research (LINEAR)
Project, operated by MIT Lincoln Laboratory on the Air Force Space Command's Space Surveillance Telescope at White Sands Missile Range, New Mexico.

Za Plutem už taky dobrý! :)

NASA’s New Horizons spacecraft is operating normally after just over 24 hours in a protective “safe mode,” the result of a command-loading error
that occurred early Thursday. The spacecraft is designed to automatically transition to safe mode under certain anomalous conditions to protect
itself from harm. In safe mode, the spacecraft suspends its timeline of activities and keeps its antenna pointed toward Earth to listen for
instructions from the Mission Operations Center at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland.
