NASA asteroid deflection test accidentally creates a BOULDER SWARM that could impact the Earth with as much energy as the Hiroshima detonation

August 11, 2023 - asteroid deflection could reach the planet at the same speed the Dimorphos boulder swarm is hurtling and cause "tremendous damage." He now wants Hubble to continue observing the asteroid swarm to help pin down their precise trajectories to see if any of them end up becoming a threat to the Earth.

"If we follow the boulders in future Hubble observations, we may have enough data to pin down the boulders' precise trajectories," said Jewitt. "And then we'll see in which ...

Asteroid that killed dinosaurs also caused GIANT tsunamis

July 16, 2021 -

Scientists at the University of Louisiana at Lafayette (UL) found these mega-ripples by means of seismic imaging carried out by a petroleum firm. They looked at soil 5,000 feet below the surface of central Louisiana and found the 50-feet-high ripples spaced half a mile apart. According to the scientists, these ripples were the imprint of the tidal waves that spread out from the asteroid's impact crater.

Furthermore, the UL scientists said the orientation of the ripples ...

‘Oumuamua asteroid may be alien technology, hints study

August 21, 2020 -

Proponents of the other theory suggest that the interstellar object, ‘Oumuamua, is a comet that is partly or entirely made up of hydrogen molecules. This could explain why astronomers were not able to detect a basic feature of a comet: a coma or a comet’s tail.

But the researchers said that this explanation ignores the fact that if ‘Oumuamua is indeed a hydrogen comet, it would have evaporated midway or early into its journey.

“We were suspicious that hydrogen ...

Our solar system’s asteroid belt is slowly FADING AWAY

October 02, 2025 -

Key points:

The ghost of a planet that never was

The story of the asteroid belt’s existence is inextricably linked to its eventual demise. When the solar system was a swirling disk of gas and dust 4.6 billion years ago, the region between Mars and Jupiter was poised to become the home of another planet. The raw materials were there, but a celestial giant had other plans. Jupiter, the solar system's behemoth, exerted a gravitational influence ...

NASA tracks house-sized asteroid amid growing celestial threats

August 17, 2025 -

The National Aeronautics and Space Administration's (NASA) Jet Propulsion Laboratory (JPL) is keeping a watchful eye on asteroid 2025 PR1, a house-sized space rock hurtling toward Earth at 17,717 miles per hour.

The asteroid passed within 609,000 miles of Earth on Saturday, Aug. 16 – closer than some satellites – but posed no immediate danger. Yet, this near-miss is part of a broader pattern: Three more asteroids are set to skim past Earth, including ...

Scientists discover 63 new young asteroid families, doubling known count

October 02, 2025 -

Researchers have identified 63 new young asteroid families – more than doubling the previously documented count – with the findings published in the journal Icarus.

Young asteroid families, clusters of space rocks formed from the breakup of larger bodies, are typically less than 10–15 million years old and consist of at least three members. Prior to this study, only 43 such families had been confirmed.

Using an advanced five-dimensional ...

Asteroid nearly collides with Earth in close call fly-by

August 24, 2020 -

The National Aeronautics and Space Administration (NASA) said that the path of 2020 QG was forever changed by the gravitational force of Earth. The asteroid is now traveling in space in a new trajectory since its close run-in.

"It's really cool to see a small asteroid come by this close because we can see the Earth's gravity dramatically bend its trajectory," said Paul Chodas, director of the Center for Near-Earth Object Studies (CNEOS) at NASA's Jet Propulsion Laboratory....

Humanity is one asteroid impact away from being wiped out

July 29, 2017 -

“Sooner or later we will get… a minor or major impact,” says Rolf Densing, head of the European Space Operations Centre (ESOC) in Darmstadt, Germany. Densing explained that even though we may not be alive to see it happen, “the risk that Earth will get hit in a devastating event one day is very high.”

Asteroid sizes range from just a few millimeters to over 6 miles in length, which astrophysicists believe is the size of the space rock that wiped out the dinosaurs millions ...

NASA draws up plans to land astronaut on doomsday asteroid

November 27, 2006 - NASA draws up plans to land astronaut on doomsday asteroid

Monday, November 27, 2006 by: Jerome DouglasTags: asteroids, astronauts, NASANASA's proposals are just at the initial stages, and the spacecraft needed to send an astronaut that far into space doesn't even exist yet. But, with a smallish asteroid called Apophis having already been identified as a possible threat to Earth in 2036, NASA is taking the exercise very seriously.Chris McKay of the NASA Johnson Space ...

Skyscraper-sized asteroid spotted near Earth deemed “potentially hazardous” by NASA

August 08, 2023 -

Experts report that 2022 SF289 is 600-foot-wide (180 meters) and orbits close enough to Earth to be classified as a potentially hazardous asteroid (PHA). The asteroid 2022 SF289 is one of an estimated 2,300 similarly classed objects.

Potentially hazardous asteroids are near-Earth objects (NEOs) that are larger than 460 feet (140 meters) in diameter.

PHAs could come within 4.65 million miles (7.48 million km) of Earth, or roughly 20 times the average distance between ...

NASA details complex mission to collect rock samples from asteroid Bennu

October 08, 2020 -

The autonomous spacecraft OSIRIS-REx will be touching down briefly on the asteroid Bennu on Oct. 20. Through its robotic arm, it will scoop rocks on the landing site Nightingale, a 52-foot rocky area in Bennu’s northern hemisphere. If all goes according to plan, the samples will be returned to Earth on Sept. 24, 2023.

The feat has only been done by the Japan Aerospace Exploration Agency. If the OSIRIS-REx mission is successful, it will be the first time the United States ...

Scientists design a new spacecraft, called a HAMMER, to carry nukes to incoming asteroids that threaten Earth

April 07, 2018 -

HAMMER stands for Hypervelocity Asteroid Mitigation Mission for Emergency Response. Each unmanned vehicle is expected to weigh around eight tons, which is less than the old Apollo spacecraft or the successor Orion system.

The American researchers published their conceptual asteroid deflection spacecraft in the journal Acta Astronautica. They will be presenting it at an asteroid-research conference in May.

Their study called for the deployment of a group ...

NASA updates its plan to deflect potentially hazardous Earth-bound asteroids

August 26, 2018 - asteroid deflection spacecraft would be fully automated. Human astronauts are, in fact, not needed to save the Earth. (Related: Ancient stone carvings depict a massive comet strike 13,000 years ago that nearly made humans extinct.)NASA is working to achieve the five goals of its asteroid deflection plan

The new plan encompassed five objectives. The first goal is a NASA-led effort to improve the ability of the U.S. to spot, follow, and identify near-Earth ...

Dinosaurs were thriving before asteroid strike — new fossil evidence challenges extinction theories

October 27, 2025 -

New research has upended long-standing assumptions about the dinosaurs' final days, revealing that these prehistoric giants were thriving right up until the asteroid impact that wiped them out 66 million years ago.

Fossils excavated from New Mexico's San Juan Basin—dated to within 300,000 years of the extinction event—show a rich and varied ecosystem, contradicting theories that dinosaurs were already in decline before their sudden demise.A ...

Astronomers warn of invisible asteroid threat to Earth lurking in Venus’s shadow

September 24, 2025 -

For decades, astronomers have warned about the dangers of near-Earth asteroids, but a new study reveals a terrifying blind spot: at least 20 massive, undiscovered space rocks lurking near Venus, each capable of wiping out a major city. These "Venus co-orbital" asteroids—some as wide as 390 meters—remain hidden in the sun’s glare, evading detection by Earth’s telescopes. And while they pose no immediate threat, their unstable orbits mean they could one ...
