Harvard Paper Explores Possibility That Object Approaching From Beyond Solar System Is Hostile Alien Technology

A strange interstellar object is hurtling its way toward our pale blue dot — and according to a Harvard astronomer, there's a chance it's not a benign asteroid or comet, but instead some harmful form of alien tech. In a new, yet-to-be-peer-reviewed paper, Harvard astronomer Avi Loeb — the same scientist who suggested that 'Oumuamua, the first interstellar object ever detected back in 2017, was alien in nature — teamed up with researchers from the Britain-based Initiative for Interstellar Studie

Our Best View Yet of Interstellar Comet 3I/ATLAS

A comet unlike any seen before has fixated astronomers around the world. An observatory in Hawaii has unveiled the most stunning image of this ancient interstellar visitor yet. The Gemini North telescope on Maunakea, Hawaii, recently snapped a close-up of 3I/ATLAS, the third interstellar object ever discovered. The telescope’s highly sensitive Multi-Object Spectrograph captured the comet’s compact coma—a cloud of gas and dust surrounding its icy nucleus—in striking detail. 3I/ATLAS is inbound t

Astronomer Says the Object Approaching Us From Beyond the Solar System Is Not What We Think

Earlier this month, astronomers were thrilled to spot an interstellar object — only the third of its kind ever observed — hurtling toward the center of the solar system on an extremely unusual trajectory and at a breakneck velocity. While we're only beginning to understand the unusual object, dubbed 3I/ATLAS, the discovery led to widespread speculation, with some scientists suggesting that it may be almost as old as the Milky Way galaxy itself, and billions of years older than our own Sun. Uns

Everything We Know About the Interstellar Object 3I/ATLAS

On July 2, NASA revealed the existence of 3I/ATLAS, only the third ever interstellar object observed in the universe. These are objects that exist in interstellar space—the areas between stars—and which are not gravitationally bound to any star. The two other interstellar objects discovered to date are the comets 1I/ʻOumuamua and 2I/Borisov. 3I/ATLAS was discovered on July 1, when its existence was reported by a telescope at Rio Hurtado in Chile, operated by the Asteroid Terrestrial Impact Aler

An Interstellar Comet Is Here, and Its Age Is Mind-Bending

This article was updated at 9:00 a.m. ET on Friday, July 11, to include new information. After defending his PhD thesis on modeling interstellar objects on Monday, June 30, Matthew Hopkins intended to take some well-deserved time off. It would appear the universe had other plans for him. The very next day, the Atlas Terrestrial-impact Last Alert System (ATLAS) telescope in Rio Hurtado, Chile, detected a mysterious object whizzing toward the Sun. Early observations suggested that it came from o

The Interstellar Visitor Hurtling Toward the Center of Our Star System Is Unimaginably Ancient, Scientists Say

Astronomers recently confirmed that a mysterious object, dubbed 3I/ATLAS, came from interstellar space and is now blowing through the solar system at extremely high speeds. It's only the third confirmed interstellar object to have reached our star system, following 'Oumuamua, which was spotted in 2018, and a comet dubbed 2I/Borisov, which was identified in tk. Now, scientists are racing to better understand 3I/ATLAS and whether it can shed more light on the nature of interstellar objects like

A Third Interstellar Visitor Is Here, and Astronomers Might Know Where It Came From

After defending his PhD thesis on modeling interstellar objects on Monday, June 30, Matthew Hopkins intended to take some well-deserved time off. It would appear the universe had other plans for him. The very next day, the Atlas Terrestrial-impact Last Alert System (ATLAS) telescope in Rio Hurtado, Chile, detected a mysterious object whizzing toward the Sun. Early observations suggested that it came from outside our solar system, potentially marking the third discovery of an interstellar object

Mysterious Object Headed Into Our Solar System Is Coming From the Center of the Galaxy

Folks, it's official: the object that astronomers recently spotted blowing through the outer solar system came from interstellar space. Yesterday, the intriguing stranger was named A11pl3Z. Now, it's earned the esteemed designation 3I/ATLAS — that "I" standing for "interstellar." 3I/ATLAS is currently located between the orbits of the asteroid belt and Jupiter, the New York Times reports, where it's about 416 million miles away from the Sun, NASA said. That's equal to four and a half times the

Confirmed: A Rare Interstellar Object Is Passing Through Our Solar System

Update: July 3, 09:24 a.m. ET: On Wednesday, July 2, the International Astronomical Union’s Minor Planet Center confirmed that an interstellar object is traveling through our solar system. Officially named 3I/ATLAS, the object appears to be a comet hurtling toward the Sun. Original article follows. Astronomers are scrambling to gather data on a mysterious object that’s currently hurtling through the solar system. Preliminary observations suggest it came from interstellar space, and if confirme

Large Object From Interstellar Space Detected Heading Toward Center of Solar System

A new interstellar object has been spotted careening into the solar system at an extremely unusual trajectory. If its interstellar origins were to be confirmed, it'd only be the third of its kind spotted in the solar system in history. An oblong interstellar object, dubbed 'Oumuamua, was first discovered in 2017, while comet 2I/Borisov was detected in 2019. The latest addition, provisionally named A11pl3Z, has a highly unusual trajectory, leading astronomers to believe it may have also origina

Interstellar Flight: Perspectives and Patience

Interstellar Flight: Perspectives and Patience This morning’s post grows out of listening to John Coltrane’s album Sun Ship earlier in the week. If you’re new to jazz, Sun Ship is not where you want to begin, as Coltrane was already veering in a deeply avant garde direction when he recorded it in 1965. But over the years it has held a fascination for me. Critic Edward Mendelowitz called it “a riveting glimpse of a band traveling at warp speed, alternating shards of chaos and beauty, the white h
