Asteroid the size of an elephant passes Earth in one of closest encounters ever | Science & Tech News
admin
An asteroid the size of an elephant has passed by Earth in one of the closest encounters ever recorded. The space rock, named 2023 BU, was projected to zoom over the southern tip of South America at about 12.29am on Friday, only 2,200 miles (3,540km) above the Earth’s surface. This makes it the fourth closest…

How to watch asteroid live stream as NASA predicts fourth closest ever near miss with Earth | World News
admin
An asteroid is due to come very close to Earth this week, passing just a few thousand kilometres above the planet’s surface. The relative near miss will be streamed live using robotic telescopes – here’s what you need to know about the asteroid and how you can watch it. What do we know about this…

Asteroid strike triggered 250-metre mega-tsunami on Mars, scientists believe | Science & Tech News
admin
A mega-tsunami on Mars could have been triggered by an asteroid strike similar to the devastating blow that wiped out the dinosaurs 66 million years ago. The giant wave, measuring up to 250 metres in height, was created about 3.4 billion years ago by the impact of an asteroid or comet in a shallow ocean…

2022 AP7: ‘Planet killer’ asteroid found hiding in sun’s glare | Science & Tech News
admin
The biggest Potentially Hazardous Asteroid (PHA) in eight years has been discovered hiding in the sun’s glare. It’s estimated at 1.5km wide – nearly a mile – a size that astronomers class as “planet killers” due to the damage they can cause. The rock is believed to be in the top 5% of largest-known PHAs.…

Dimorphos asteroid being trailed by 6,000 miles of debris after impact by NASA’s DART spacecraft | Science & Tech News
admin
More than 6,000 miles of debris is trailing behind an asteroid that was deliberately hit by a NASA spacecraft. The image was captured by a telescope in Chile two days after last month’s Double Asteroid Redirection Test (DART). It shows a tail made up of dust and other material from the impact by the spacecraft…

NASA smashes spacecraft into asteroid seven million miles from Earth in ‘planetary defence’ trial | Science & Tech News
admin
NASA has successfully smashed a spacecraft into an asteroid seven million miles from Earth. The last image from the “vending machine-sized” collider showed the surface of the asteroid Dimorphos seconds before impact. The Double Asteroid Redirection Test (DART) is the first-ever trial of a “planetary defence system”. If the orbit of an asteroid can be…

Why NASA is crashing a spacecraft into a harmless asteroid at 14,000mph tonight | Science & Tech News
admin
A harmless asteroid millions of miles away is about to be rammed by a NASA spacecraft at 14,000mph. Why? The fate of the human race could one day depend on doing the same. It has been 66 million years since an asteroid crashing into the Earth brought an end to the reign of the dinosaurs,…

NASA-built spacecraft to deliberately crash into asteroid in test mission | Science & Tech News
admin
A NASA-built spacecraft will deliberately crash into an asteroid as part of a test mission later this month. The spacecraft, known as Double Asteroid Redirection Test (Dart), is expected to collide with a 170-metre wide (560ft) asteroid named Dimorphos at 12.14am UK time on 27 September. Dimorphos is no threat to Earth but it has…
