The Hubble group has actually launched a sensational brand-new image snapped by the NASA/ESA Hubble Space Telescope of the interstellar comet 3I/ATLAS, which is just the 3rd item of its kind ever observed.
This picture of the interstellar comet 3I/ATLAS was taken by Hubble on November 30, 2025. At the time, the comet had to do with 286 million km(178 million miles)from Earth. Image credit: NASA/ ESA/ STScI/ D. Jewitt, UCLA/ M.-T. Hui, Shanghai Astronomical Observatory/ J. DePasquale, STScI.
3I/ATLAS was found by the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) study telescope in Rio Hurtado, Chile, on July 1, 2025.
At the time, the interstellar comet was at a heliocentric range of 4.51 huge systems (AU), with an eccentricity of 6.13.
Understood as C/2025 N1 (ATLAS) and A11pl3Z, the things got here from the instructions of the constellation Sagittarius, and is moving with a really high radial speed of around 58 km (36 miles) per second.
3I/ATLAS made a close method to Mars at a range of 0.194 AU on October 3 and reached its closest method to the Sun– called perihelion– on October 30.
The interstellar visitor will be approaching Jupiter at a range of 0.357 AU on March 16, 2026.
On November 30, the astronomers utilized Hubble’s Wide Field Camera 3 (WFC3) instrument to observe 3I/ATLAS.
“Hubble tracked the comet as it crossed the sky,” they stated in a declaration.
“As an outcome, background stars look like streaks of light.”
“Hubble formerly observed 3I/ATLAS in July, soon after its discovery, and a variety of NASA objectives have actually because studied the comet also.”
“Observations are anticipated to continue for a number of more months as 3I/ATLAS goes out of the Solar System.
“The image reveals a teardrop-shaped radiant halo that extends towards the Sun,” stated Harvard University’s Professor Avi Loeb about the brand-new Hubble image.
“This sunward anti-tail extension was likewise obvious in the pre-perihelion Hubble image, handled July 21, as 3I/ATLAS was approaching the Sun from a range that is 56% bigger from Earth.”
“The brand-new radius of the radiance has to do with 40,000 km (24,855 miles) and its anti-tail extension heads out to about 60,000 km (37,282 miles).”
“In a current paper, I recommended that the teardrop of the coma in post-perihelion pictures of 3I/ATLAS is related to a great deal of macroscopic non-volatile things that separated from it as an outcome of its determined non-gravitational velocity far from the Sun,” he stated.
“I anticipated that by November 30th, the swarm of items would be closer to the Sun than 3I/ATLAS by about 60,000 km if the things overlapped with 3I/ATLAS at perihelion.”
“This separation remains in ideal arrangement with the anti-tail extension of the teardrop shape in the brand-new Hubble image.”
