You’ll Need all the Internet to Download the Full Resolution of this New Running Chicken Nebula Image

The Running Chicken Nebula comprises several clouds, all of which we can see in this vast image from the VLT Survey Telescope (VST), hosted at ESO’s Paranal site. This 1.5-billion pixel image spans an area in the sky of about 25 full Moons. Image Credit: ESO/VST

Over 6,000 light-years from Earth, an open star cluster and its nebula cover a swathe of sky over 270 light-years across. It’s called the Running Chicken Nebula, and it’s more than just one object. The Running Chicken Nebula, also called IC 2944, also contains IC 2948, the brightest part of the Chicken, as well as several Bok Globules and smaller nebulae. The bright star Lambda Centauri is near the visual center of the Chicken but is actually much closer to Earth.

Webb Sees a Supernova Go Off in a Gravitationally Lensed Galaxy – for the Second Time

NASA’s James Webb Space Telescope has spotted a multiply-imaged supernova in a distant galaxy designated MRG-M0138. Image Credit: NASA, ESA, CSA, STScI, Justin Pierel (STScI) and Andrew Newman (Carnegie Institution for Science).

Nature, in its infinite inventiveness, provides natural astronomical lenses that allow us to see objects beyond the normal reach of our telescopes. They’re called gravitational lenses, and a few years ago, the Hubble Space Telescope took advantage of one of them to spot a supernova explosion in a distant galaxy.

Now, the JWST has taken advantage of the same lens and found another supernova in the same galaxy.

Psyche Gives Us Its First Images of Space

NASA’s Psyche mission began eight weeks ago when it launched from the Kennedy Space Center. While it won’t reach its objective, the metal-rich asteroid Psyche, until 2029, the spacecraft has already travelled 26 million km (16 million miles.) During that time, it’s already had its share of success as it ticks off items on its checklist of tests.

Now, we have our first images from Psyche. And while they don’t show us anything about its eventual target, they give us a behind-the-scenes look at how complex spacecraft prepare themselves as they cruise toward their destinations.

China’s Space Station, Seen from Orbit

When the Space Age dawned in 1957, there were only two players: the USA and the USSR. The USA won the space race by being first to the Moon, though the USSR enjoyed its own successes. But here we are only a few decades later, and the USSR appears to be fading away while China is surging ahead.

Nothing’s more emblematic of China’s surge than its Tiangong space station.

JWST Reveals a Newly-Forming Double Protostar

This new Picture of the Month from the NASA/ESA/CSA James Webb Space Telescope reveals intricate details of the Herbig Haro object 797 (HH 797). HH 797 dominates the lower half of this image. The bright infrared objects in the upper portion of the image are thought to host two further protostars. This image was captured with Webb’s Near-InfraRed Camera (NIRCam).

As our newest, most perceptive eye on the ongoing unfolding of the cosmos, the James Webb Space Telescope is revealing many things that were previously unseeable. One of the space telescope’s science goals is to expand our understanding of how stars form. The JWST has the power to see into the cocoons of gas and dust that hide young protostars.

It peered inside one of these cocoons and showed us that what we thought was a single star is actually a binary star.

Webb’s Infrared Eye Reveals the Heart of the Milky Way

The full view of the NASA/ESA/CSA James Webb Space Telescope’s NIRCam (Near-Infrared Camera) instrument reveals a 50 light-years-wide portion of the Milky Way’s dense centre. An estimated 500,000 stars shine in this image of the Sagittarius C (Sgr C) region, along with some as-yet unidentified features. Image Credit: NASA, ESA, CSA, STScI, S. Crowe (UVA)

The JWST is taking a break from studying the distant Universe and has trained its infrared eye on the heart of the Milky Way. The world’s most powerful space telescope has uncovered some surprises and generated some stunning images of the Milky Way’s galactic center (GC.) It’s focused on an enormous star-forming region called Sagittarius C (Sgr C).

Juno Completes its Closest Flyby of Io Yet

Not since the Galileo mission ended 20 years ago have we seen such great images of Io. NASA's Juno spacecraft captured this image with its JunoCam instrument on October 15th from less than 12,000 km altitude. Ted Stryk processed the image. Image Credit: Ted Stryk/NASA/JPL-Caltech/SwRI/MSSS/

Jupiter’s ocean moons capture most of our attention because of their potential habitability. But Io, Jupiter’s bad-boy volcanic moon, is in a class of its own. There’s nothing else like it in the Solar System, and NASA’s Juno spacecraft captured new images of the volcanic satellite during its closest approach yet.

Feast Your Eyes on this Star-Forming Region, Thanks to the JWST

Nature is stingy with its secrets. That’s why humans developed the scientific method. Without it, we’d still be ignorant and living in a world dominated by superstitions.

Astrophysicists have made great progress in understanding how stars form, thanks to the scientific method. But there’s a lot they still don’t know. That’s one of the reasons NASA built the James Webb Space Telescope: to coerce Nature into surrendering its deeply-held secrets.

A Last-Minute Addition to the Solar Orbiter Allows it to See More Deeply into the Sun’s Atmosphere

Spacecraft instruments are highly specialized and can take years to design, build, and test. But a last-minute hack to one of the instruments on the ESA’s Solar Orbiter has allowed the spacecraft to take some difficult observations it would otherwise have been unable to take.

It’s all because of one astronomer and an instrument door.

The Sun Gets Meteor Showers Too, But They’re Very Different

The Sun dominates the Solar System in almost every way imaginable, yet much of its inner workings have been hidden from humanity. Over the centuries, and especially in the last few decades, technological advancements allowed us to ignore our mothers’ exhortations and stare at the Sun for as long as we want. We’ve learned a lot from all those observations.

A new study shows how the Sun experiences its own ‘meteor showers.’
