A giant star may have destroyed itself in one of the universe’s rarest explosions

Astronomers may have discovered one of the clearest examples yet of a rare “pair-instability” supernova. It is a catastrophic explosion thought to completely destroy some of the most massive stars in the universe, leaving behind no remnant. The paper outlining the properties of this rare explosion was posted to the arXiv preprint server on May 15.

‘A pretty significant setback’: How Blue Origin’s rocket explosion affects NASA’s moon plans

The explosion of Blue Origin’s New Glenn rocket is a big setback for the spaceflight company and will have implications for NASA’s plans to return astronauts to the surface of the moon. Continue Reading‘A pretty significant setback’: How Blue Origin’s rocket explosion affects NASA’s moon plans

Longest-period young transiting exoplanets discovered

It’s 2234, you’re on your annual class field trip touring exoplanets, and your teacher informs everyone they can pick one more exoplanetary system to explore before heading back to Earth. You and your classmates are exhausted from the day’s activities and you’re hungry. However, you get really excited because you already know what everyone will want. You and your classmates all shout in unison, “The young and far away puffy ones!”

June 2026: What’s in the sky this month? Venus and Jupiter have a spectacular conjunction, and the Moon occults Venus

Mercury reaches greatest elongation in the evening sky this month. Venus and Jupiter have a spectacular conjunction, and later in the month the Moon occults Venus. Meanwhile, Jupiter drops deeper into twilight as it sinks toward next month’s conjunction with the Sun. The morning sky hosts ever-more-prominent Saturn, while Mars and Uranus meet in Taurus.Continue reading “June 2026: What’s in the sky this month?

June 2026: What’s in the Southern Hemisphere sky this month?

June evenings offer a great chance to view three bright planets. Jupiter, Venus, and Mercury gather in the northwestern sky as darkness settles in, creating a grand sight to the naked eye and worthy targets through a telescope. Jupiter has been wandering through Gemini the Twins since the dawn of 2026. Shining at magnitude –1.9,Continue reading “June 2026: What’s in the Southern Hemisphere sky this month?” The post June 2026: What’s in the Southern Hemisphere Continue ReadingJune 2026: What’s in the Southern Hemisphere sky this month?

Roman Telescope’s massive infrared mirror is ready to fly

It’s June 2027, and you’re fresh off defending your PhD studying the direct imaging of exoplanets while starting your postdoctoral journey at NASA Jet Propulsion Laboratory. The trauma of eating ramen and living off a sub-living wage for the last five years of your life is still fresh in your brain. But you’re excited to finally get your real career started with funding you received for viewing time on the much-anticipated Nancy Grace Roman Space Telescope (Roman for short). You begin to download the first set of data as your eyes tear up knowing your entire journey in research and academia is about to be worth it.

JWST Finds Methane Atmosphere on Temperate Exoplanet

It’s 2165, and methane is in high demand, especially after the Titan Treaty of 2145 made it illegal to harvest methane from Saturn’s moon, Titan. But the advent of interstellar travel has made exoplanetary exploration far easier, enabling corporations to identify and harvest methane from exoplanets. However, it’s far cheaper and easier to harvest methane from exoplanets with reasonable (also called temperate) temperatures, because it means higher quantities of methane. The Exoplanet Exploration Corporation decides to send its first ship to one such exoplanet loaded with methane that could bring their quarterly financial statements back into the green.

Blue Origin’s Lunar Lander Just Passed Its Toughest Test Yet

Before any spacecraft can survive the Moon, it has to survive something almost as brutal, a giant metal chamber in Houston that strips away every molecule of air and swings temperatures from scorching to freezing in minutes. Blue Origin’s lunar lander just spent time in exactly that chamber and it came out the other side ready for the real thing.

The Loudest Planet Wins

We are closer than ever to detecting signs of life on another world. The James Webb Space Telescope is already ‘sniffing’ alien atmospheres, and the Habitable Worlds Observatory is being built specifically to find biology beyond Earth. But a new paper raises an uncomfortable question; when we do find that first biosignature, will it actually tell us anything meaningful about life in the universe? The answer, it turns out, might be no.

Did We Invent Dark Energy for Nothing?

For nearly thirty years, dark energy has been cosmology’s great get out of jail free card, the invisible, mysterious force we invented to explain why the universe is expanding faster than it should be. Now a team of mathematicians says we may never have needed it at all. And the implications are stranger than you might think.

The Galaxy That Forgot to Spin

Every galaxy we know of spins. It’s one of those rules of the universe so fundamental that astronomers barely think about it anymore. So when the James Webb Space Telescope pointed at one of the most massive galaxies in the early universe and found…well nothing. No spin, just stillness. They had to look twice.

Supermassive black holes could be the universe’s biggest planet nurseries

Supermassive black holes are the largest known black holes in the universe, sitting at the center of most large galaxies. They are sometimes described as cosmic monsters because they feed on surrounding gas and dust when they are active, as well as destroy anything that gets too close. But their reputation could be due for a rethink, as a new paper published on the arXiv preprint server suggests they may also be the birthplace of millions of planets.

It Took a Cosmic Village to Shape Early Galaxies

An early galaxy cluster named after an Indian lake is teaching astronomers about influences on galaxy evolution in the infant Universe. Astronomer Ronaldo Laishram of the National Astronomical Observatory of Japan (NAOJ) used the Subaru Telescope’s wide-field camera, Hyper Suprime-Cam (HSC), to conduct a large sky survey to look for early galaxies with active star formation. The result was the discovery of a massive protocluster of galaxies that existed some 12.6 billion years ago, very early in cosmic time. Detailed study of this region could give new insight into how galaxies and their clusters form and evolve.

May 31, 1975: ESA begins operations

In the 1960s, two organizations were formed for cooperation around a European presence in space: the European Space Research Organization, which focused on scientific research, and the European Launcher Development Organization, which concentrated on engineering launch systems. By the end of the decade, however, dissatisfaction was growing with this split structure, and in 1968, theContinue reading “May 31, 1975: ESA begins operations” The post May 31, 1975: ESA begins operations appeared first on Astronomy Magazine.
