An interstellar object is heading towards Earth, scientist warns
Loeb bases his theory on the object's unusual brightness, which implies a diameter of 20 km, and a glow observed in front of it, unlike the trailing tail of typical comets.
He noted that it would take 10,000 years for such a massive object to naturally arrive in the inner solar system, and that it will be unobservable when closest to Earth.
31/ATLAS is only the third interstellar object ever detected in our solar system, confirmed to have originated outside it.
Loeb has a history of similar controversial claims, having previously theorised an alien origin for Oumuamua in 2017 and for a meteor recovered in 2023, though other astrophysicists have offered natural explanations for these phenomena.

What is Chiron? The asteroid currently in retrograde
You might have seen an interesting phrase popping up in your social media feeds lately: 'Chiron is in retrograde.' If you're anything like me, you've never heard of Chiron before – and I'm a professional astronomer. So what is Chiron, and what does it mean to be in retrograde? The short answer is that Chiron is an asteroid -slash-comet orbiting somewhere past Jupiter and Saturn. And until January 2026, it's going to look like it's going backwards in the sky. If you can spot it. But there's a bit more to the story. What is Chiron? Chiron's official name is (2060) Chiron. First things first: it's pronounced 'kai-ruhn', with a hard K sound. It was discovered by astronomer Charles Kowal in 1977. This was long after the system of Western astrology was developed, which probably explains why people who check their daily horoscopes are also blissfully unaware of its existence. It was initially classified as an asteroid or a rock in space. In 1989, astronomers discovered that Chiron sometimes has a tail or 'coma', which tells us that it's actually a comet or a 'dirty snowball'. Since then, Chiron has been classified as both an asteroid and a comet. In 2023, more than 45 years after it was first discovered, astronomers confirmed that Chiron has rings. This makes it the fourth non-planet in the Solar System to have rings. (The planets Jupiter, Saturn, Uranus and Neptune have rings, as do the asteroid Chariklo and the dwarf planets Haumea and Quaoar.) Chiron orbits the Sun in an oval-shaped orbit. The closest it gets to the Sun is about 1.3 billion kilometres (about eight times the distance between Earth and the Sun) and the furthest it gets from the Sun is a whopping 2.7 billion km (about 19 times the distance between Earth and the Sun). This puts it between the orbits of Jupiter and Uranus, cutting through the orbit of Saturn. Centaurs in space Chiron is a member of the Centaurs. This is a group of small Solar System bodies that orbit the Sun between Jupiter and Neptune. Their orbits are highly unstable: they change over time because of gravitational interactions with the giant planets. In Greek mythology, centaurs were creatures with the lower body and legs of a horse and the torso and arms of a human. Chiron was the oldest centaur, the son of the Titan Kronos. He was considered the wisest centaur. Fans of Percy Jackson and the Olympians may also recognise Chiron as the director of Camp Halfblood. Chiron in retrograde In astronomy, retrograde motion is when something is going backwards compared with everything else. Apparent retrograde motion is where an object in the sky, such as a planet, appears to be going backwards when we look at it from Earth. The object hasn't actually changed direction; it just looks like it from our perspective. All the planets (and Chiron) orbit the Sun in the same direction. This means the planets typically look like they are moving in a west-to-east direction across the sky. But when Earth 'catches' up to a planet (or a planet catches up to Earth) and overtakes it, the planet temporarily appears to move in a west-to-east direction in the sky. This temporary illusion is apparent retrograde motion. It's just like when you're driving in a car and overtake a slower car, that slower car looks like it's going backwards as you overtake it. Chiron went into retrograde (that is, apparent retrograde motion) on July 30, 2025, and will go back to normal on January 2, 2026. But unless you have a telescope or do some long-exposure photography, you'd never know which way Chiron is travelling. Chiron is very faint, so you can't see it with your eyes. The ancient astrologers didn't know about Chiron, but I like to think they'd appreciate a centaur in space with a ring on it.

Northern Lights warning for August 8 and 9 2025 as solar flare hits
Exact best time to see the lights as Met Office raises hopes the aurora borealis could return tonight Star watchers and holidaymakers are being told to watch the skies tonight as a solar flare is expected to create a big northern lights display. The Met Office space forecast said that an Coronal Mass Ejection and coronal hole fast wind influence is forecast for August 8-9 adding to the likelihood of an astral event in Scotland's skies. Digital Camera World said that active sunspot could mean the aurora borealis could return this weekend. The aurora borealis, also known as the northern lights, is a natural light display in the sky caused by charged particles from the sun colliding with the Earth's atmosphere, primarily oxygen and nitrogen molecules, which then emit light. This creates a vibrant, dancing display of colors in the sky. The Met Office said: 'Expected Coronal Mass Ejection and coronal hole fast wind influence is forecast for 08-09 August, which will likely enhance auroral activity. Sightings are possible over Scotland, especially the north, given clear skies. 'There is a chance of visible activity for parts of the north of England and Ireland given good conditions, with the peak chance likely from late on 08 August. However, confidence in the timing remains low, and visibility will be limited by the short hours of darkness and any potential cloud cover. Aurora activity likely declining by the end of the period.' Digital Camera World added: 'An active sunspot could give photographers another reason to photograph the night skies this weekend. A solar flare that hit on August 05 increases the odds of seeing the Northern Lights as its effects reach Earth, with the National Oceanic and Atmospheric Administration predicting KP levels above 4.0 could hit on Friday, August 08. 'The levels indicate increased probability of spotting the northern lights in states like Michigan and Maine, as well as parts of Canada. While the odds are still fairly low, the prediction comes as the Perseids meteor shower is gaining in intensity – and photographing some meteors could be a consolation prize if the aurora doesn't make an appearance. 'The coronal mass ejection hurled from an active sunspot launched a bit sidewise, which lowers the odds of seeing the effects dancing across the night sky compared to solar activity flung straight towards Earth. Despite the unusual direction, the activity is enough for NOAA to predict a potential minor G1 storm.' The optimal time to witness the Northern Lights is usually between 10.30pm and 2am. Aurora displays are a result of charged particles colliding with gases in Earth's atmosphere near the magnetic poles.

The mysterious 'dark comets' prowling our Solar System
These strange objects could explain how water arrived on Earth, but may also be a previously unrecognised threat to our planet. Now, a spacecraft is headed towards one to investigate. They are some of the strangest rocks in our Solar System. They aren't quite asteroids and not quite comets, but a bizarre mixture of the two. These are "dark comets" – and no-one knows quite what to make of them. Yet, these mysterious, recently discovered space rocks might be an entirely new class of object in the Solar System that could help to answer questions about how water originated on Earth, according to the scientists trying to study them. They may also pose a previously unrecognised threat to our planet. And now we have a chance of finding out more about these strange objects thanks to a Japanese spacecraft racing towards one – by complete coincidence – right at this moment. When it gets there in 2031, we might find out for certain what exactly these objects are and how they behave. The first hint of dark comets emerged in 2016, when astronomers found what they thought was an asteroid that behaved like a comet. While asteroids are rocky, inactive objects commonly found in a wide belt between the planets Mars and Jupiter, comets are rock and ice that have huge tails stretching for millions of miles and tend to originate from the outer solar system.
