An NEA is an asteroid whose orbit brings it within 195 million kilometres of the Sun, meaning that it can pass within 50 million kilometres of Earth’s orbit. Just like planets, these asteroids typically orbit the Sun. While most of the asteroids in the solar system are in the “main belt” between Mars and Jupiter. […]

This week is a happy one for all the UFO enthusiasts out there as a declassified version of the United States defence-intelligence report on UFOs is expected to be made public in the coming days. While it is unlikely that we will hear about aliens in the report, it could still present interesting insights into […]

Astronomers have spotted three near-Earth asteroids (NEAs) hiding in the glare of the Sun. One of these asteroids is the largest “potentially hazardous” object spotted in the last three years, according to NOIRLab. Asteroids hiding in the Sun’s glare The asteroids were discovered using twilight observations made with the Dark Energy Camera at the Cerro […]

Sometimes it is hard to remember that we and everyone we know live on a rock that is rapidly moving across an endless and mysterious place that we still know very little about—space. From a gamma-ray burst sweeping across our planet due to the birth of a star to how some stars give a “warning” […]

For an asteroid to be classified as a near-Earth Asteroid (NEA), its trajectory should bring it within 1.3 Astronomical Units (AU) of the Sun. One AU is the distance between the Sun and our planet. According to the European Space Agency (ESA), over 30,000 NEAs have been discovered so far, with most of the discoveries […]

OSIRIS-REx, NASA’s first spacecraft designed for returning an asteroid sample, began its two-year journey back to Earth in 2021 and it is now on track to deliver a sample of the asteroid Bennu back to our planet on September 24, 2023. Here is how NASA plans to execute the “parcel drop” back to Earth. Precise […]

The extinction of dinosaurs was triggered when a 10-kilometre asteroid hit Earth around 66 million years ago, according to the Geological Society of America (GSA). Scientists have uncovered new evidence that the Chicxulub impact also triggered a “mega-earthquake that released about 100 billion trillion joules of energy, or about 50,000 times more energy than was […]

NASA will make its first attempt to crash into an asteroid on September 26 or September 27, 2022, depending on where you live in the world. The collision will mark the end of the DART mission, a 10-month space journey to autonomously deflect a non-hazardous asteroid. But it will also the start of masses of […]

NASA has revealed that 101955 Bennu, an asteroid discovered back in 1999, has a surface that can be compared to a play area for kids, complete with loosely packed particles that make up the entire exterior of the asteroid. “It turns out that the particles making up Bennu’s exterior are so loosely packed and lightly […]

A ‘potentially hazardous’ asteroid, which is twice the size of the Burj Khalifa and four times the Empire State Building will zip past Earth on Friday, according to NASA’s Centre for Near Earth Object Studies. The asteroid, named 1989 JA, is estimated to be 1.1 miles long, two kilometres wide and is travelling at a […]
