According to astronomers, several asteroids with diameters more than 10 meters collide with the surface of the solar system’s largest planet every year, causing explosions visible from Earth. Previously, such collisions were registered in 1,994 2009, 2,010 2012, 2,016 2017 and 2019.

If confirmed, this will be the ninth recorded impact on Jupiter since the first in July 1,994 when Comet Shoemaker-Levy 9 shattered into several smaller pieces, sinking one after another into the giant’s gas shell, leaving dark marks on the clouds of Jupiter, some of them the size of our planet.

NASA has a launch date for that most Hollywood of missions, the Double Asteroid Redirection Test, which is basically a dry run of the movie “Armageddon.” Unlike the film, this will not involve nukes, oil rigs or Aerosmith, but instead is a practical test of our ability to change the trajectory of an asteroid in a significant and predictable way.

The DART mission, managed by the Planetary Defense Coordination Office (!), involves sending a pair of satellites out to a relatively nearby pair of asteroids, known as the Didymos binary. It’s one large-ish asteroid, approximately 780 meters across — that’s Didymos proper — and a 160-meter “moonlet” in its orbit.

As the moonlet is more typical of the type likely to threaten Earth — there being more asteroids that are that size and not easily observed — we will be testing the possibility of intercepting one by smashing into it at nearly 15,000 miles per hour. This will change the speed of the moonlet by a mere fraction of a percent, but enough that its orbit period will be affected measurably. Knowing exactly how much will help us plan any future asteroid-deflection missions — not surprisingly, there isn’t a lot of existing science on ramming your spacecraft into space rocks.

North Korea fired at least one ballistic missile from its eastern coast on Tuesday morning, according to South Korean and Japanese officials.

The launch took place in the port city of Sinpo, Hamgyong province, at about 10 a.m. local time Tuesday (9 p.m. ET Monday), South Korea’s Joint Chiefs of Staff (JCS) said. In a text to reporters, the JCS said it appeared to be a submarine-launched ballistic missile (SLBM).

South Korea’s Defense Ministry said the missile is estimated to have been fired from the sea, but has yet to confirm whether it was launched from a submarine. Sinpo is home to a North Korean naval shipyard.

Is Planetary Defense PI in the Sky?

In February of 2,013 skywatchers around the world turned their attention toward asteroid 2012 DA14, a cosmic rock about 150 feet (50 meters) in diameter that was going to fly closer to Earth than the spacecraft that bring us satellite TV.

Little did they realize as they prepared for the once-in-several-decades event that another bit of celestial debris was hurtling toward Earth, with a more direct heading. On February 15 2013, the Chelyabinsk meteor, a roughly 62-foot (19 meter)-diameter asteroid exploded over the city of Chelyabinsk, Russia, as it entered Earth’s atmosphere at a shallow angle. The blast shattered windows and damaged buildings, and nearly two thousand people were hurt, though thankfully no one died.

Talking about RejuvenateBio starts at 20:30. Mentions there are 300 known genes concerning human aging and 45 of those have been tested in mice with what sounds like success.


Wow! Where do I start. I woke up and seen Dr. George Church on Bloomberg news. They was discussing a new biotech startup company called Rejuvenate Bio. A life extension company that seeks to reverse aging in dogs. Then apply that knowledge to humans. I ask Dr. Church about what he thinks is the cause of aging. t. Dr. Church thinks its a genetic reason why we age. Dr. Church is a cofounder of a company called Colossal is a company that wants to create a hybrid between the east asian elephant and the woolly mammoth. The purpose of doing this is to fight climate change and prevent the extinction of the east asian elephant.

As technology rapidly progresses, some proponents of artificial intelligence believe that it will help solve complex social challenges and offer immortality via virtual humans.

But AI’s critics are sounding the alarm, going so far as to call its development an “existential threat” to mankind. Is this the stuff of science fiction? Could the “Terminator” become reality, or will these fears prevent the next technological revolution?

Our planet is in crisis.

From increasing storms, wild fires and extinctions, to the pollution of our water and the possible failure of our food systems, we are on the brink of a disaster of epic proportions.

Can we decarbonise our lifestyles?

Could we even be better off carbon free?


Can We Save Our Planet.

What can we do to save our planet for the future?
Amazingly it may be easier and cheaper than you think.

Sixty-three percent. That’s the proportion of mammal species that vanished from Africa and the Arabian Peninsula around 30 million years ago, after Earth’s climate shifted from swampy to icy. But we are only finding out about it now. — HeritageDaily — Archaeology News.
