    Meteor shower, a comet and the Moon: What's in the sky this month

    The beginning of May heralds the peak of the annual Eta Aquariids meteor shower. 

    The Eta Aquariids usually put on a good show, but this year they peak a few days after a full moon so they will be much harder to see than usual.

    If you are really keen, you still may catch a few fireballs if you're awake before sunrise on May 6 and 7.

    Tanya Hill, an astronomer at the Melbourne Planetarium, says the Eta Aquariids do not produce many meteors that are bright enough to beat glare from the Moon.

    The Eta Aquarid meteor shower brings shooting stars before dawn, the Moon meets brilliant Venus after sunset, and May wraps up with a rare Blue Moon.

    Shooting stars before dawn, a brilliant meetup between the Moon and Venus, and a rare “Blue Moon” to end the month.

    First up: the Eta Aquarid meteor shower, which peaks in early May.

    These shooting stars come from Halley’s Comet. Every year, Earth passes through the comet’s dusty trail, and those tiny particles burn up in our atmosphere. That’s what creates those bright streaks across the sky.

    Halley’s Comet last passed through the inner solar system in 1986, and won’t return until 2061.

    The First Radio Signal From Comet 3I/Atlas Ends the Debate About Its Nature

    More evidence has emerged to support the natural origin of comet 3I/Atlas. After several weeks of conspiracy theories, social media debates, and speculation on popular podcasts such as Joe Rogan's, this interstellar object is still a comet. The most recent confirmation came from an observatory in South Africa that detected the first radio signal from 3I/Atlas.

    But how? A radio signal? That would have to confirm the object is technlogical in nature, wouldn't it? The thing is, this isn't a radio signal like a transmission emitted by a spacecraft. It's instead a radio frequency pattern detected by MeerKAT, a radio telescope composed of 64 antennas—each with a diameter of 13.5 meters—operated by the South African Radio Astronomy Observatory. And what did it detect? "OH absorption was detected on the 1665 MHz and 1667 MHz lines," according to the researchers.

    The Remarkable Large-Scale Structure of Anti-Tail and Tail Jets from 3I/ATLAS

    Today, a magnificent large-scale image of the interstellar object 3I/ATLAS, was reported here by Frank Niebling and Michael Buchner. The stacked image combines a series of 5 exposures, each lasting 3 minutes, from two telescopes (TEC 140/f5 and ASI 6200MM) between 5:08–5:23 UT on November 9, 2025.

    The image shows two anti-tail jets out to 10 arcminutes towards the Sun accompanied by a longer collimated jet, extending away from the Sun out to an angular separation of 30 arcminutes, roughly the diameter of the Sun or the Moon.

    At the current distance of 3I/ATLAS from Earth, 326 million kilometers, these angular extents correspond to spatial sizes of 0.95 million kilometers for the sunward anti-tail jets and 2.85 million kilometers for the tail jet away from the Sun. This enormous spatial scale is three orders of magnitude larger than the scale of the glowing halo around 3I/ATLAS in the Hubble Space Telescope image from July 21, 2025 (reported here).
