Astronomers left disappointed as green comet meets fiery end before it can be seen
Originating from the distant Oort Cloud, far beyond Pluto, the comet had been captivating observers with its distinctive tail, visible through telescopes and binoculars.
However, experts now believe the icy wanderer likely fragmented as it swung past the sun, rapidly diminishing its brightness and dashing hopes of naked-eye visibility.
'We'll soon be left with just a dusty rubble pile,' astrophysicist Karl Battams with the U.S. Naval Research Laboratory said in an email.
Comets are balls of frozen gas and dust from billions of years ago. Every so often, a comet passes through the inner solar system.
'These are relics from when the solar system first formed,' said Jason Ybarra, director of the West Virginia University Planetarium and Observatory.
The newest comet was discovered by amateur astronomers, who spied it in photos taken by a camera on a spacecraft operated by NASA and the European Space Agency to study the sun.
The comet won't swing close to Earth like Tsuchinshan-Atlas did last year. Other notable flybys included Neowise in 2020 and Hale-Bopp and Hyakutake in the 1990s.
The comet, also designated C/2025 F2, would have been visible just after dark slightly north of where the sun set. Its green color would have been difficult to see with the naked eye.
This might have been the object's first ever trip past the sun, making it particularly vulnerable to breaking apart, Battams said. After its flyby, what's left of the comet will disappear into the outer reaches of the solar system, past where scientists think it came from.
'It's going to go so far out that we have no idea if it's ever going to return,' said Battams.

Venus and Jupiter Conjunction 2025: Two brightest planets to 'meet up' in the sky
Calling all skygazing fans, there's a real treat in store later this month. Despite being millions of miles apart, Venus and Jupiter will look as if they're close to bumping into each other in the night sky this planetary meet up is known as the conjunction and it takes place over several 2025, the planets will appear closest over the 11 and 12 August. When can I see the Venus and Jupiter Conjunction? A conjunction is when two planets appear close together or even touching in the night sky as seen from Venus and Jupiter conjunction is a rare opportunity to see two of the brightest planets in the Milky Way, side by to the Royal Observatory Greenwich, Venus will outshine Jupiter with its white glow, while Jupiter will appear more best time to see this happen is in the early morning sky on Tuesday 12 order to best see this, if you can, find a high spot and look for two dazzlingly bright spots very close don't need a telescope and you should be able to see it with the naked eye or the event, the two planets will go their separate ways as they begin to drift apart again in the night makes it more special, is that the conjunction is not the only space event to look forward to in the night sky on that day, at around 9pm, the Perseid meteor shower is due to to Nasa, during this time, it could be possible to see up to 100 meteors an hour. Five top facts about Venus 1. Venus is the hottest planet in our solar system and the brightest object after the Sun and our Moon, which means on a clear night you might be able to see it without using a telescope.2. Because of this, people have known about its existence for centuries and Venus was the first planet to be reached from Earth by a spacecraft.3. Venus is named for the ancient Roman goddess of love and beauty. Most features on Venus are named for women. It's the only planet named after a female god.4. Venus is the slowest spinning planet in our solar system, meaning one day on Venus is the same as 243 days on Earth.5. But for Venus to orbit the Sun takes around 225 Earth days, which means that a year on Venus is shorter than its day! Five top facts about Jupiter 1. Jupiter is the oldest and largest planet in the Milky Way - it's so big you could fit around 1,000 Earths inside it!2. It's also the fastest rotating planet too, with one day only lasting 9.9 hours - meaning it has the shortest day of any planet in the solar system.3. Jupiter doesn't have a solid surface and is mostly made up of swirling gases and liquids, giving it the name 'gas giant'. 4. It has winds that have been known to travel up to 400mph that swirl around the planet giving it bands and stripes.5. Its most famous feature is its 'Red Spot', which is a storm that's so big it is visible from Earth with a telescope. It's thought to have been raging for 300 years!

Manhattan-sized object spotted in space 'could be alien spacecraft heading to attack Earth'
A draft scientific paper has proposed that the object, 3I/ATLAS, might be alien technology and could make a surprise attack on our planet An object the size of Manhattan could potentially be a hostile alien spacecraft set to attack Earth in November, according to a worrying recent study. Earlier this month, experts confirmed the sighting of a rare interstellar visitor, only the third ever detected, speeding through our Solar System at an incredible pace. The comet is known as 3I/ATLAS, and was formerly referred to as A11pl3Z. A draft scientific paper published on Tuesday suggests that the object might actually be extraterrestrial technology planning a surprise attack on our planet. The researchers propose that the object's orbit is such that it would allow an intelligent alien craft to approach Earth undetected. The report alleges that when it reaches its closest point to the Sun in late November, the object will be concealed from Earth's view, enabling it to execute a covert high-speed manoeuvre to decelerate and remain in the Solar System, secretly preparing for an attack. Scientists note that 3I/ATLAS follows an unusual trajectory that brings it very close to planets like Venus, Mars, and Jupiter, an event highly unlikely to occur by chance, with less than a 0.005 per cent probability, reports the Mirror. One of the authors of the paper, which has yet to undergo peer review, is Avi Loeb, a renowned Harvard astrophysicist recognised for his controversial research and outspoken views on the search for extraterrestrial intelligence. He gained widespread attention for suggesting that the 2017 interstellar object 'Oumuamua might be an artificial probe created by an alien civilisation, based on its unusual acceleration and shape His co-authors are Adam Hibberd and Adam Crowl from the Initiative for Interstellar Studies in London. The authors emphasise that their paper is a theoretical exercise rather than a reflection of their personal beliefs. They state: "This paper is contingent on a remarkable but, as we shall show, testable hypothesis, to which the authors do not necessarily ascribe, yet is certainly worthy of an analysis and a report." However, the authors warn: "The consequences, should the hypothesis turn out to be correct, could potentially be dire for humanity, and would possibly require defensive measures to be undertaken (though these might prove futile)." The study further adds: "The hypothesis is an interesting exercise in its own right, and is fun to pursue, irrespective of its likely validity." The celestial body, now officially named 3I/ATLAS (), is thought to originate from a distant star system and is hurtling through space at speeds exceeding 60 kilometres per second. The object was initially detected on July 1 by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey telescope located in Río Hurtado, Chile. It's estimated that 3I/ATLAS measures between 10 and 20 kilometres across, although it could appear smaller if it's largely made up of reflective ice. Last month, a Scottish teenager was left stunned after spotting a 'UFO' in the skies over Midlothian. Kyle Jackson, 16, and his two pals saw the mysterious floating object overhead at around 11.10pm on Friday, June 6. The trio were walking near Newbattle High School in Easthouses, just outside Edinburgh, when they looked up and were left gobsmacked by what they saw. Kyle said the round and "completely silent" black object appeared to be moving below the clouds at speeds faster than a plane. Join the Daily Record WhatsApp community!

Night Sky: There's still time to spot some noctilucent cloud activity
Nick managed to photograph the event as the Sun's rays reached out from far below the horizon, lighting up tiny frozen water droplets high up in the Earth's atmosphere. The result is this stunning image incorporating long wispy white clouds tinged with blue. Taken from the Latin for 'night-shining', the clouds can be seen a couple of hours after sunset looking to the northwest. One of the richest and most bountiful of the annual meteor displays is underway as the Perseids fire themselves up for another outburst in August. While the shower will be covered in more detail as we head toward the night when maximum activity is expected, meteors from the display have already commenced as the Earth ploughs through a field of rocky debris left by a comet. The densest part of the field will be encountered on the night of August 12 into August 13, when we could witness up to 150 meteors per hour. This is a perfect opportunity to see some celestial fireworks, all of which can be observed with the naked eye. While the position of Mars in the evening sky hasn't made for the best of viewing, there's a chance to spot both the red planet and a crescent Moon on Monday July 28, low above the western horizon at around 10pm. This will be one of the last opportunities to see Mars this year as during August it will slip into the twilight and won't be seen again until 2026. Meanwhile, the morning sky continues to be dominated by Venus. Space news, and the Hubble Space Telescope has caught the first glimpse of 3I/Atlas, just the third object humanity has witnessed entering our solar system from beyond its limits. The 12-mile-wide 'invader', larger than the asteroid that eventually led to the downfall of the dinosaurs, is due to pass Mars in October and Earth in December, both fly-bys posing no threat. Thought to have been formed seven billion years ago, 3I/Atlas is currently speeding through our solar system at 150,000 mph. Tuesday July 22 saw the Earth complete a spin on its axis at 1.34 milliseconds less than the standard 24 hours, making for the second fastest rotation since records began in 1973. For a significant part of Earth's history a day on Earth was approximately 19 hours long, but over time, the day has become constantly longer due to affects such as the relationship with the Moon and the associated tidal forces. However, just to buck the trend! Founded in 1975, Cardiff Astronomical Society currently has an exhibition running at Cardiff Museum. One of the largest and most active astronomical societies in the UK, the event, which showcases the work of the society throughout the decades and its established links to the community, is free to enter, running until October 31.
