Earth

A huge asteroid the size of 90 elephants has been spotted hurtling towards Earth. The enormous space rock measures between 120m and 270m, meaning it could be taller than the Gherkin in London – or the size of up to 90 elephants.

NASA will introduce four astronauts who are headed to the Moon. The four — three Americans and one Canadian — will be the crew of Artemis II, a 10-day mission occurring no earlier than the end of 2024 that will travel around the moon before heading back to Earth.

Aliens could be hiding in special 'terminator zonnes' on distant planets where it is not too hot and not too cold, scientists say.

All good things come to an end, including NASA’s wildly successful Artemis 1 mission to the Moon and back. At least, it’s been successful so far, as Orion must still perform a harrowing reentry through Earth’s atmosphere. Here is when and where you can follow the action live.

Measuring about 65 feet in height, the asteroid will pass within 4 million kilometres of Earth. That's a long way, but if anything unexpected happens, it may be covered in a few days at its top speed of 15,408 kilometres per hour.

NASA's Artemis spacecraft has successfully arrived at the moon after finally blasting off from Earth last week. The spacecraft also sent back images of Earth looking extremely tiny like a 'pale blue dot' from 230,000 miles( 370149.12 km) away. Check them out.

NASA's new moon rocket blasted off on its debut flight with three test dummies aboard early Wednesday, bringing the U.S. a big step closer to putting astronauts back on the lunar surface for the first time since the end of the Apollo program 50 years ago.

Chinese rocket debris weighing 23 tons has crashed to Earth in an uncontrolled descent Friday. U.S. Space Command tweeted a confirmation that the rocket re-entered the Earth's atmosphere over the south-central Pacific Ocean at 4:01 a.m. Friday.

A solar eclipse takes place when the moon passes between the sun and the earth, obstructing the sun's light from reaching the earth. With this, the moon casts a shadow on the earth, resulting in a solar eclipse.

It is also advised that the eclipsed Sun should not be viewed with the naked eye even for a very brief period of time. Even when the Moon blocks the majority of the Sun, it will still damage the eyes permanently and result in blindness.
