Origin of dinosaur-ending asteroid possibly found. And it’s dark

Posted by in categories: asteroid/comet impacts, existential risks

Scientists figured out what slammed into Earth and killed the dinosaurs 66 million years ago: a giant dark primitive asteroid from the outer reaches of the solar system’s main asteroid belt.

SpaceTime Series 24 Episode 91
*Astronomers zero in on source of the impactor that wiped out the dinosaurs.
A new study claims the impactor believed to have wiped out and 75 percent of all life on Earth 66 million years ago including all the non-avian dinosaurs — likely came from the outer half of the main asteroid belt between Mars and Jupiter.
*Producing matter out of pure energy.
Scientists have directly converted pure light energy into matter in a single process for the first time.
The findings reported in the journal Physical Review Letters involved the creation of Electrons and their antimatter counter parts positrons — by colliding quantum packets of photons – light particles.
*Discovery of a galactic stream of galaxy clusters.
Astronomers have discovered a never-before-seen galaxy cluster with a black hole at its centre, travelling at high speed along an intergalactic road of matter.
*Solar Orbiter and BepiColombo making space history with double flyby of Venus.
As we go to air tonight the European Space Agency is making space history with two of its space craft6 undertaking almost simultaneous flybys of the planet Venus.

New US congressional report says COVID-19 leaked out of Chinese Government Wuhan Lab.
Wearing masks and social distancing even when vaccinated key to combat new COVID strains.

NBD, There’s Just a Massive Asteroid Hurtling Past Earth This Month

Posted by in categories: asteroid/comet impacts, existential risks

Should you be worried about the massive space rock that could, theoretically, spell disaster if it were to make landfall on terra firma? No, you shouldn’t. But that doesn’t mean you should ignore it either.

The asteroid, called 2016 AJ193, is just under a mile wide and moving at a speed of 58538 miles per hour, according to EarthSky. Its closest encounter with Earth will occur on August 23 at 11:10 a.m. ET, and experts note that anyone trying to spot the asteroid in the wild will have the best chance of doing so before sunrise. If you’re trying to catch a glimpse of it, you’ll have to use a telescope.

Despite the “potentially hazardous” label designated by NASA, EarthSky is quick to allay any fears of impending apocalypse (at least from this particular asteroid) because it won’t hit Earth.

Asteroid the size of the Great Pyramid of Giza just flew (safely)

Posted by in categories: asteroid/comet impacts, existential risks

😀


An asteroid about as long as the Great Pyramid of Giza is tall made a “close” approach with Earth on Sunday (July 25), according to NASA calculations.

There is no worry that the space rock poses any threat to Earth, but NASA monitors such rocks to both learn more about the early solar system — asteroids are rocky fragments from that time — and because if their orbits were to change, the asteroid could pose a future risk to Earth.

Repurposed communications satellites could help save humanity from an asteroid impact

Posted by in categories: asteroid/comet impacts, existential risks, satellites

What do you do if you discover a big rock on a collision course with Earth and have very little time to take action?


Large telecommunication satellites used for TV broadcasting could be quickly and easily repurposed as anti-asteroid weapons according to European aerospace company Airbus.

NASA approved a space telescope that could save Earth from an asteroid

Posted by in categories: asteroid/comet impacts, existential risks

NASA finally approves the launch of an infrared asteroid hunting space telescope able to locate threats 30M miles away…


NASA has approved the Near-Earth Object Surveyor space telescope to help the space agency be better prepared for future asteroids that could pose a threat to Earth.

The 20-foot-long infrared telescope would help astronomers and planetary scientists find ‘most’ of the potentially hazardous asteroids and comets that come within 30 million miles of Earth’s orbit, also known as near-Earth objects (NEOs).

Where do meteorites come from? A new study challenges popular theory

Posted by in categories: asteroid/comet impacts, existential risks

By knowing where meteorites come from, we can protect the Earth from asteroid collisions.


After examining 10000 kilograms of sedimentary rock, a new study suggests that meteorites come from an unidentified region in the asteroid belt.

In a NASA simulation of an asteroid impact, scientists concluded they couldn’t stop a space rock from decimating Europe

Posted by in categories: asteroid/comet impacts, existential risks

Scientists around the world have been bamboozled this week by a fictitious asteroid heading toward Earth.

A group of experts from US and European space agencies attended a week-long exercise led by NASA in which they faced a hypothetical scenario: An asteroid 35 million miles away was approaching the planet and could hit within six months.
