SOHO spots water gushing from interstellar comet 3I/ATLAS after its Sun pass

SOHO spots water gushing from interstellar comet 3I/ATLAS after its Sun pass

Scientists using the SOHO spacecraft measured water production from interstellar comet 3I/ATLAS peaking at 3.17 x 10^29 molecules per second in early November 2025, then dropping sharply by December. The data, posted as a preprint, provide rare post-perihelion measurements for only the third confirmed interstellar object to enter the solar system. NASA says the comet poses no threat to Earth.

Interstellar comet 3I/ATLAS spills its secrets as scientists clock its water loss and radio silence

Astronomers measured water streaming from interstellar comet 3I/ATLAS after its November 2025 solar flyby, with SOHO data showing a peak rate of 3.17×10^29 molecules per second. Breakthrough Listen reported no credible narrowband radio technosignatures from the object. NASA said the comet will not approach closer than 1.8 AU to Earth. Amateur astronomers continue attempts to photograph it.

Interstellar Comet 3I/ATLAS: December 2025 Close Approach, New Hubble Images and ‘Ice Volcano’ Surprises

NASA and ESA released new images and data on interstellar comet 3I/ATLAS, showing unexpected activity as it nears its closest approach to Earth later this month. Hubble captured the comet’s bright core and dust halo from 178 million miles away, while ESA’s Juice spacecraft also recorded fresh images. Scientists say 3I/ATLAS is only the third confirmed interstellar object and is older than the Solar System.

Interstellar Comet 3I/ATLAS: Cryovolcanoes, Expanding Coma and ‘Heartbeat’ Pulses – Latest Updates as of December 3, 2025

Astronomers report interstellar comet 3I/ATLAS is erupting with ice volcanoes and shows a symmetric coma without a visible tail, unlike typical comets. The object displays a 16.16-hour brightness cycle, fueling debate about its origins. Viral images show a star-like blob as it approaches Earth, coming closest on December 19 at 170 million miles. 3I/ATLAS is only the third confirmed interstellar comet.

Comet 3I/ATLAS Today: NASA’s Big Image Reveal, ISRO’s New Data and How to Follow the Interstellar Visitor (Nov. 19, 2025)

NASA will unveil its sharpest images yet of interstellar comet 3I/ATLAS at 3 p.m. ET Wednesday during a live event from Goddard Space Flight Center. India’s ISRO released new data from its Mount Abu telescope, showing classic comet activity and familiar molecular signatures. Scientists estimate 3I/ATLAS may be over 8 billion years old, far predating the solar system.

Alien Probe or Cosmic Relic? Interstellar Comet 3I/ATLAS Baffles Scientists (updated 27.10.2025)

3I/ATLAS Today (Nov. 13, 2025): Interstellar comet’s tail keeps growing, ‘radio signal’ confirmed natural, and a different ATLAS comet fragments

A new analysis confirms the recent “radio signal” from 3I/ATLAS is due to natural comet outgassing, not technology, according to data from South Africa’s MeerKAT array. Images show 3I/ATLAS remains intact after perihelion, while a separate comet, C/2025 K1 (ATLAS), is visibly fragmenting in new observations.

MeerKAT Detects Radio Signal From Interstellar Comet 3I/ATLAS — OH Lines Confirm Natural Origin (Nov. 13, 2025)

South Africa’s MeerKAT radio array detected hydroxyl absorption lines at 1665 and 1667 MHz from interstellar comet 3I/ATLAS on Oct. 24, 2025, confirming water outgassing as it neared the Sun. The signal matches classic comet chemistry and counters recent speculation about artificial origins. Earlier September attempts saw no signal. The finding marks the first radio confirmation for 3I/ATLAS.

Interstellar Comet 3I/ATLAS Stuns Scientists with Surprising Bright Outburst and Ancient Origins

Comet 3I/ATLAS, discovered July 1, 2025 by the ATLAS survey in Chile, is only the third known interstellar object to enter the solar system. The comet brightened rapidly as it passed the Sun on October 29, baffling astronomers and revealing strong outgassing of water vapor and carbon dioxide. It will not approach closer than 1.8 AU from Earth. Analyses suggest 3I/ATLAS may be nearly 10 billion years old.

  • Sensex Drops Nearly 800 Points as Oil Prices Rebound and Iran-US Ceasefire Concerns Return
    April 9, 2026, 1:04 AM EDT. The BSE Sensex slumped 794.65 points (1.02%) to 76,768.25, while the Nifty 50 fell 196.55 points (0.82%) to 23,800.80 on Thursday. Gains from the previous session's relief rally, sparked by a temporary Iran-US ceasefire and falling crude oil prices, reversed sharply. The rebound in crude oil prices renewed inflation fears, pressured the rupee and corporate margins, dampening investor sentiment. Analysts noted the ceasefire remains fragile and the market's recovery vulnerable if oil prices spike again. Heavyweight stocks including HDFC Bank, Infosys, and Reliance Industries dragged the indices down. The decline underscores continued volatility driven by geopolitical risks and oil price fluctuations, with markets reacting to headlines rather than fundamentals.
