The latest images of comet 3I/ATLAS are in, delivering a glorious view of the interstellar object’s burgeoning tail, courtesy of NOIRLab’s powerful Gemini South telescope. This bodes well for astronomers keen to see the emergence of long, well-defined cometary tails as 3I/ATLAS shimmies towards its closest approach to the Sun, or perihelion – a rendezvous calculated to occur around 29 …

The first interstellar object to visit the solar system may have been a fragment of an icy exoplanet, research suggests. When 1I/’Oumuamua was first spotted in 2017, astronomers quickly determined that it came from outside the solar system. But although it was initially classified as a comet from another star system, it may actually be the skin of an “exo-Pluto,” …

Astronomers worldwide are turning their focus to a rare and baffling cosmic visitor: interstellar object 3I/ATLAS. First detected in early July as it sped toward the Sun from deep space, the object is only the third interstellar body ever observed in human history, following ʻOumuamua in 2017 and Comet Borisov in 2019. Now, four powerful space-based observatories, NASA’s Hubble Space …

By definition, scientists don’t know what to expect as they inspect the interstellar object 3I/ATLAS, since it’s only the third object detected from beyond the solar system in human history. But the surprises just keep coming. The mysterious entity, which was first spotted hurtling towards the Sun from far beyond in early July, has fascinated researchers ever since. As Science Alert …

The core of Jupiter, the largest planet in our solar system, has long been a source of mystery for astronomers: an object so unfathomably dense and hot that it defies comprehension. Conventional theories have suggested for years that the gas giant’s behemoth interior was formed following an enormous collision with an early planet. The “giant impact” theory suggests that roughly half …

When NASA’s Dawn mission arrived at Ceres in 2015, scientists and the general public got their first detailed look at this strange and beautiful planetoid. As the largest object in the Main Asteroid Belt, accounting for more than 39 percent of its total mass, Ceres is the only object in the belt that has undergone hydrostatic equilibrium (aka. became round …

A new study has returned to a popular Milky Way attraction, formed by a fast-spinning dead star core that scientists say is one of the most powerful electromagnetic generators in the galaxy.  At the heart of this colorful nebula is a so-called pulsar, a type of neutron star that blasts streams of high-energy particles through space as it revolves like …

A prominent Harvard astrophysicist has claimed that a mysterious object moving through our solar system could be a nuclear-powered spacecraft.  Professor Avi Loeb, director of the Galileo Project, which hunts for signs of extraterrestrial intelligence, said the interstellar object known as 3I/ATLAS exhibits characteristics suggesting it is not a typical comet, contrary to NASA’s assessment.  One of those signs is …
