Astronomers detected Elias 2-24 b in professional images made with a coronagraph, then confirmed it by comparing archived observations from different years. NASA described it in September 2026 as the youngest known exoplanet, at less than one million years old. That does not mean it is visible to the naked eye or through an ordinary backyard telescope: NASA says the planet is at the limit of what current telescopes can detect.
Why Elias 2-24 b is notable
Elias 2-24 b is a newborn planet still embedded in the gas-and-dust disk surrounding its host star, Elias 2-24. NASA’s September 2026 account describes it as less than one million years old and roughly as massive as Jupiter. Its star is about 450 light-years from Earth. These are approximate descriptions; the cited reports do not give a detailed set of measurement uncertainties.
The planet sits in a prominent gap in the disk. Such gaps are consistent with the idea that forming planets can shape the material around them, although this one system does not by itself establish exactly how the gap formed. NASA quotes lead researcher Andrea Bernardi: “The planets should be found within the gaps, since they are carving them. And that’s exactly where we found Elias 2-24 b.” NASA Science, September 16, 2026.

It is also still accreting material, giving astronomers a rare chance to study a giant planet while it is forming rather than only after its early growth has ended.

How astronomers confirmed the planet
The confirmation came from revisiting observations already stored in the Keck Observatory Archive. Researchers found Elias 2-24 b in coronagraph observations from 2018 and 2020. Rather than treating one faint point of light as conclusive, they compared its position across observations. Its motion was consistent with an object orbiting the star, not an imaging artifact or a background star.
- Suppress the star’s glare. A coronagraph blocks or reduces light from the bright host star, making it easier to detect a much fainter nearby source.
- Check older observations. The team found the candidate in archival Keck data from 2018 and 2020.
- Compare its position over time. The source’s changing position helped distinguish a real orbiting object from a defect in the images or a distant background star.
This was a direct-imaging confirmation, not a report that astronomers found the planet by watching it pass in front of its star. The method matters because a single faint spot can be ambiguous; evidence of motion across years strengthens the case that the source is physically associated with the system. The discovery was reported by NASA Science and W. M. Keck Observatory.
What “seeing” the planet means
Here, “seeing” means detecting a faint source in professional astronomical data—not looking up at the star and spotting the planet. NASA says Elias 2-24 b is at the limit of what current telescopes can detect. The cited discovery reports do not establish an unaided-eye or consumer-telescope viewing method, so buying a backyard telescope is not a way to see this particular exoplanet.

A coronagraph helps professional instruments separate faint planetary light from the host star’s glare; researchers then analyze the images and compare observations. The detection therefore depends on specialized equipment and careful data analysis, rather than simply pointing an ordinary telescope at Elias 2-24.

What this discovery says about planet formation
Because Elias 2-24 b is both extremely young and still gathering material, it offers a view of giant-planet formation in progress. Its presence in a disk gap also gives scientists a chance to examine how young planets and their surrounding disks influence one another.
The finding challenges existing explanations for how quickly planets can form, but it does not settle on a new mechanism. NASA quoted co-author Lucas Cieza: “Elias 2-24 b shows us that even our best planet-formation models are still missing some important processes.” Cieza also noted that the previous youngest-known exoplanets were more than five million years old. The result is evidence that models need to account for something they currently miss—not proof of precisely what that process is.
Rank #4
Could future telescopes make detections easier?
NASA’s September 2026 report says the Nancy Grace Roman Space Telescope launched on August 30, 2026, and describes its coronagraph as a more powerful instrument that could make faint-planet detections easier. Bernardi told NASA: “Elias 2-24 b is at the limit of what current telescopes can detect, but with new instruments like NASA’s Nancy Grace Roman Space Telescope, such detections should become easier.” This is a prospect for the broader study of faint planets, not a promise that Roman will observe Elias 2-24 b or resolve every open question about this system.
