Harvard astrophysicist⁢ Avi Loeb says​ NASA has ‌not yet​ released images⁢ of interstellar comet 3I/ATLAS taken by the HiRise camera on the Mars ⁢Reconnaissance Orbiter, despite expectations they⁣ would be available in October 2023. ⁤Loeb believes these images may hold‍ clues about the⁣ comet’s unusual​ behaviour, specifically​ the jets observed emanating​ from⁢ it.

Loeb stated in ‍early October that⁣ the images,captured ⁢around the time of the federal government⁣ shutdown,could provide answers regarding the object’s composition and origin.

What is 3I/ATLAS?

3I/ATLAS is the third ⁤interstellar object ⁤confirmed to have entered our solar system.‍ The designation “3I” signifies this,while “ATLAS” acknowledges its discovery by⁣ the ​ Asteroid terrestrial-impact Last Alert System (ATLAS) observatory in Hawaii. ATLAS ⁢is ‍designed‌ to scan the night⁣ sky for near-Earth objects, including asteroids and comets.

Unlike most comets ‌originating ‍from the outer ⁤reaches of our solar system (like the Oort Cloud or⁤ Kuiper Belt),⁣ 3I/ATLAS​ comes ⁣from *outside* our solar system, making it⁤ a rare opportunity for study. ‍it was first observed in ‍June 2023 ⁢and ‌is currently traveling through the inner solar system.

Why the ⁢Interest in⁢ 3I/ATLAS?

Interstellar objects‌ like 3I/ATLAS offer ⁤a unique window into the composition of planetary systems around other ‌stars. Analyzing its properties can⁢ provide ⁣insights​ into the materials‍ and conditions present in ‌those distant systems.‌ Loeb, known for his ‍research on interstellar objects⁤ like⁢ ‘Oumuamua, has consistently advocated for a more thorough examination of these visitors.

The observation of jets emanating from 3I/ATLAS is particularly intriguing. ⁤ Cometary​ jets are streams of gas and dust released as the comet approaches the Sun and its ‍icy components sublimate. however, the characteristics‍ of⁤ these jets, ‍and whether they​ differ from those observed in solar system comets, could reveal clues about ⁢the object’s origin and internal structure.

The ​HiRise Camera and the Mars Reconnaissance Orbiter

The HiRise (High ‍Resolution Imaging Science Experiment) ‍camera is a ⁤powerful instrument aboard the‌ mars Reconnaissance ⁢Orbiter (MRO). While ⁤primarily designed to image the surface ‍of Mars in high ⁢detail, ⁤HiRise can also be used to observe⁤ objects passing through its⁤ field ‍of ⁣view. its high resolution makes it potentially capable ⁢of capturing details about 3I/ATLAS that might not‌ be visible with other telescopes.

the⁣ timing‌ of the images, taken during the government shutdown, has ⁣raised questions about the‌ prioritization of data ⁣release.loeb‍ suggests the images were taken but have not⁢ been made public.
