Catch this week's supermoon, biggest and brightest of year

  Catch this week's supermoon, biggest and brightest of year CAPE CANAVERAL, Fla. — A supermoon rises in the sky this week, looking to be the biggest and brightest of the year. Not only will the moon be closer to Earth than usual, it will also be a full moon. Scientists call this cosmic combo a supermoon. The moon will be 221,855 miles (357,042 kilometres) away at its fullest Tuesday night, making it appear larger and more brilliant. NASA is encouraging everyone to look skyward, whether it’s outside or through a living room window. Scientist Noah Petro of NASA's Goddard Space Flight Center in Maryland said the important thing is to stay safe while moon-gazing during the pandemic. “If you can’t get out safely ... then fine," Petro said.

As part of its OSIRIS-REx mission, the Nasa will attempt to collect a sample of the asteroid Bennu to bring it back to our planet. It is the very first attempt to collect a sample to return to Earth ever organized by the United States space agency. This first test will take place on October 20, announced this Wednesday NASA in an release .

Toronto's Inside Out LGBTQ film festival postponed to October

  Toronto's Inside Out LGBTQ film festival postponed to October TORONTO — Inside Out, which is billed as Canada's largest LGBTQ film festival, has been postponed until October. Organizers say the Toronto event originally scheduled for May will now go ahead from Oct. 1-11 due to the COVID-19 crisis. All purchased tickets and packages will remain valid for the new October dates. Organizers say some festival initiatives will still take place online during the original festival dates of May 21-31. They include Inside Out's LGBTQ international feature film financing forum and the annual short film pitch competition.

Since arriving at the asteroid last December, NASA 's OSIRIS-REx mission has been mapping its surface to determine the best spot to collect samples next year. The asteroid is much more rugged than expected, so four potential sites where the spacecraft can "tag" Bennu were chosen with care.

NASA is sending a probe to the asteroid Bennu to collect samples from the space rock and return them to Earth. How to sample an asteroid . In August 2018, OSIRIS-REx will meet up with Bennu , which "We really want to understand this phenomenon so that we can better understand asteroid

The asteroid Bennu, whose trajectory crosses the orbit of the Earth, is said to have formed at the same time as the planets of our solar system. As the Numerama site explains, its exploration could allow us to advance knowledge about the origins of these planets.

A sample of a few tens of grams

Currently in orbit around Bennu, the space probe OSIRIS-REx is responsible for taking a sample of about 60 grams, directly on the surface of the asteroid. The sampling site, called Nightingale, is located in a crater 140 meters wide.

If all goes well, a dedicated mechanism of OSIRIS-REx will come into contact with the surface of the asteroid for about 5 seconds, time to send out a pressurized nitrogen discharge and recover a sample of material.

Rehearsal next August

Originally, this sampling was scheduled for August 25. But the constraints imposed by the coronavirus epidemic forced the space agency to postpone the mission, in order to allow the teams to prepare properly.

A final rehearsal is scheduled for August 11: on this occasion, the space probe will perform the first three maneuvers planned during the sample collection, just 40 meters from the surface of the asteroid. The OSIRIS-REx mission should then leave the asteroid in mid-May 2021.

Tagish Lake meteorite that fell in northern B.C. contains clues as to how life may have arisen on Earth .
On Jan. 18, 2000, a fireball lit up the morning sky over Yukon and northern British Columbia. Loud bangs shook the area, and dust clouds wafted in the upper atmosphere. The culprit: a five-metre rock that entered Earth's atmosphere at more than 105 km/h. While most of the roughly 105-tonne meteor broke up on entry, some fragments showered down to the frozen landscape, much of it on Tagish Lake, B.C. Fortunately for astronomers, with the lake being frozen, many of the fragments were able to be collected. Now, a fragment of the meteorite from the Royal Ontario Museum's collection may be shedding some light on how life could have been brought to Earth.
