Red Giant Star U Camelopardalis Blows a Bubble | Hubble

A bright star is surrounded by a tenuous shell of gas in this unusual image from the NASA/European Space Agency Hubble Space Telescope. U Camelopardalis, or U Cam for short, is a star nearing the end of its life. As it begins to run low on fuel, it is becoming unstable. Every few thousand years, it coughs out a nearly spherical shell of gas as a layer of helium around its core begins to fuse. The gas ejected in the star’s latest eruption is clearly visible in this picture as a faint bubble of gas surrounding the star.

U Cam is an example of a carbon star. This is a rare type of star whose atmosphere contains more carbon than oxygen. Due to its low surface gravity, typically as much as half of the total mass of a carbon star may be lost by way of powerful stellar winds.

Located in the constellation of Camelopardalis (The Giraffe), near the North Celestial Pole, U Cam itself is actually much smaller than it appears in Hubble’s picture. In fact, the star would easily fit within a single pixel at the center of the image. Its brightness, however, is enough to overwhelm the capability of Hubble’s Advanced Camera for Surveys making the star look much bigger than it really is.

The shell of gas, which is both much larger and much fainter than its parent star, is visible in intricate detail in Hubble’s portrait. While phenomena that occur at the ends of stars’ lives are often quite irregular and unstable, the shell of gas expelled from U Cam is almost perfectly spherical.

The image was produced with the High Resolution Channel of the Advanced Camera for Surveys.

A Tour of Giant Star AG Carinae in Carina | Hubble

A Tour of Giant Star AG Carinae in Carina | Hubble

Space Sparks Episode 3: This video showcases AG Carinae—a star in the constellation Carina. It is classified as a luminous blue variable (LBV) and is one of the most luminous stars in the Milky Way. It shines with the brilliance of 1 million suns. AG Carinae is a few million years old and resides 20,000 light-years away. This giant star is waging a tug-of-war between gravity and radiation to avoid self-destruction. The star is surrounded by an expanding shell of gas and dust—a nebula—that is shaped by the powerful winds emanating from the star. The nebula is about five light-years wide, equal to the distance from here to our nearest star, Alpha Centauri.

AG Carinae is formally classified as a Luminous Blue Variable because it is hot (blue), very luminous, and variable. Such stars are quite rare because there are not many stars that are so massive. Luminous Blue Variable stars continuously lose mass in the final stages of their life, during which a significant amount of stellar material is ejected into the surrounding interstellar space, until enough mass has been lost that the star has reached a stable state. 

AG Carinae is surrounded by a spectacular nebula, formed by material ejected by the star during several of its past outbursts. The nebula is approximately 10,000 years old, and the observed velocity of the gas is approximately 70 kilometers per second. While this nebula looks like a ring, it is in fact a  hollow shell rich in gas and dust, the center of which has been cleared by the powerful stellar wind travelling at roughly 200 kilometers per second. The gas (composed mostly of ionised hydrogen and nitrogen) is visible to us in these images as a thick bright red ring, which appears doubled in places—possibly the result of several outbursts colliding into each other. The dust, here visible in blue, has formed in clumps, bubbles and filaments that are shaped by the stellar wind.

Scientists who observed the star and its surrounding nebula note that the ring is not perfectly spherical; it appears to have a bipolar symmetry, indicating that the mechanism producing the outburst may have been caused by the presence of a disc in the center, or that the star is not alone but might have a companion (known as a binary star). An alternative and simpler theory is that the star rotates very fast (as many massive stars have been found to do).

Flight to Maisie's Galaxy: 3D Time Travel | James Webb Space Telescope

This 3D visualization portrays about 5,000 galaxies within a small portion of the CEERS (Cosmic Evolution Early Release Science) Survey, which gathered data from a region known as the Extended Groth Strip. As the camera flies away from our viewpoint, each second amounts to traveling 200 million light-years into the data set, and seeing 200 million years further into the past. The appearances of the galaxies change, reflecting the fact that more distant objects are seen at earlier times in the universe, when galaxies were less developed. The video ends at Maisie’s Galaxy, which formed only 390 million years after the big bang, or about 13.4 billion years ago.

The Science of Snow: Digging for Data | NASA Goddard

The Science of Snow: Digging for Data | NASA Goddard

It takes a lot of field work in challenging conditions to gather important snow data. This is the story of NASA’s last SnowEx campaign and those who participated in it. In March 2023, scientists traveled to research sites in the northern tundra and in Fairbanks, Alaska. Ground crews looked to validate data collected from airborne instruments, while the flight crews continued collecting snow data in order to see what instruments best measure snow globally.

The goal for SnowEx is to determine the best remote-sensing techniques for a potential future satellite. Snow data is extremely important and can tell us things like how much spring runoff can be expected, which is vital for water resource management.

Distant Galaxy Cluster eMACS J1353.7+4329: "The Monster Mash" | Hubble

Distant Galaxy Cluster eMACS J1353.7+4329: "The Monster Mash" | Hubble

The NASA/European Space Agency Hubble Space Telescope has captured a monster in the making in this observation of the exceptional galaxy cluster eMACS J1353.7+4329, which lies about eight billion light-years from Earth in the constellation Canes Venatici. This disturbed collection of at least two galaxy clusters is in the process of merging together to create a cosmic monster, a single gargantuan cluster acting as a gravitational lens.

Image Description: A cluster of elliptical galaxies, visible as a dense crowd of oval shapes, each glowing orange around a bright core. Right of the largest, central galaxy, a background galaxy is stretched into two connected, thin arcs by the cluster’s gravity. Various other galaxies are dotted all around, a few being small spirals. A bright star with four long spikes stands out at the right.

Gravitational lensing is a dramatic example of Einstein’s general theory of relativity in action. A celestial body such as a galaxy cluster is sufficiently massive to distort spacetime, which causes the path of light around the object to be visibly bent as if by a vast lens. Gravitational lensing can also magnify distant objects, allowing astronomers to observe objects that would otherwise be too faint and too far away to be detected. It can also distort the images of background galaxies, turning them into streaks of light. The first hints of gravitational lensing are already visible in this image as bright arcs which mingle with the throng of galaxies in eMACS J1353.7+4329.

The data in this image are drawn from an observing proposal called Monsters in the Making, which used two of Hubble’s instruments to observe five exceptional galaxy clusters at multiple wavelengths. These multi-wavelength observations were made possible by Hubble’s Wide Field Camera 3 and Advanced Camera for Surveys.

Bright Blue Variable Star Eta Carinae | European Southern Observatory

Bright Blue Variable Star Eta Carinae | European Southern Observatory

This image of the luminous blue variable star Eta Carinae was taken with the NACO near-infrared adaptive optics instrument on the European Southern Observatory's Very Large Telescope (VLT), yielding an incredible amount of detail. The images clearly shows a bipolar structure as well as the jets coming out from the central star.

Eta Carinae is located 7,500 light-years away in the constellation Carina. It is within the Carina Nebula, a giant star-forming region in the Carina–Sagittarius Arm of the Milky Way. Despite its large distance from Earth, Eta Carinae briefly became the second brightest star in the sky in the mid-nineteenth century (with an apparent magnitude -1), surpassed only by Sirius.

The Paranal Observatory’s NAOS+CONICA instrument, better known as NACO, is one of the best ground-based solutions to atmospheric turbulence. Thanks to its pioneering use of Adaptive Optics, NACO delivers images as sharp as if we were in space.

The image was obtained by the Paranal Science team and processed by Yuri Beletsky (ESO) and Hännes Heyer (ESO). It is based on data obtained through broad (J, H, and K; 90 second exposure time per filters) and narrow-bands (1.64, 2.12, and 2.17 microns; probing iron, molecular and atomic hydrogen, respectively; 4 min per filter).

Unstable Star Eta Carinae: K-band (Infrared) View | European Southern Observatory

Unstable Star Eta Carinae: K-band (Infrared) View | European Southern Observatory

Eta Carinae is one of the heaviest and most luminous stars known. Its mass probably exceeds 100 solar masses, and the star is about 4 million times brighter than the Sun. Such a massive star has a comparatively short lifetime of about a million years. When measured in the cosmic timescale, Eta Carinae must have formed quite recently. This star is highly unstable and prone to violent outbursts. 

These outbursts are caused by the very high radiation pressure at the star's upper layers, which blows significant portions of the matter at the "surface" into space during eruptions that may rage for several years. The last of these outbursts occurred between 1835 and 1855, peaking in 1843. 

Eta Carinae is located 7,500 light-years away in the constellation Carina. It is within the Carina Nebula, a giant star-forming region in the Carina–Sagittarius Arm of the Milky Way. Despite its large distance from Earth, Eta Carinae briefly became the second brightest star in the sky at that time (with an apparent magnitude -1), surpassed only by Sirius.

This image is an infrared narrow K-band image of the massive star Eta Carinae. The image quality is difficult to estimate because the central star saturated the detector, but the clear structure of the diffraction spikes and the size of the smallest features visible in the photo indicate a near-diffraction limited performance. The field measures about 6.5 x 6.5 square arcsec.

In infrared astronomy, the K band is an atmospheric transmission window centered on 2.2 μm (in the near-infrared 136 THz range).

Preview of a Supernova in Binary Star System Eta Carinae | Hubble

Preview of a Supernova in Binary Star System Eta Carinae | Hubble

At the turn of the 19th century, the binary star system Eta Carinae was faint and undistinguished. In the first decades of the century, it became brighter and brighter, until, by April 1843, it was the second brightest star in the sky, outshone only by Sirius (which is almost a thousand times closer to Earth). In the years that followed, it gradually dimmed again and by the 20th century was totally invisible to the naked eye. Eta Carinae is located 7,500 light-years away in the constellation Carina. It is within the Carina Nebula, a giant star-forming region in the Carina–Sagittarius Arm of the Milky Way.

The star has continued to vary in brightness ever since, and while it is once again visible to the naked eye on a dark night, it has never again come close to its peak of 1843.

The larger of the two stars in the Eta Carinae system is a huge and unstable star that is nearing the end of its life, and the event that the 19th century astronomers observed was a stellar near-death experience. Scientists call these outbursts supernova impostor events, because they appear similar to supernovae but stop just short of destroying their star.

Although 19th century astronomers did not have telescopes powerful enough to see the 1843 outburst in detail, its effects can be studied today. The huge clouds of matter thrown out a century and a half ago, known as the Homunculus Nebula, have been a regular target for Hubble since its launch in 1990. This image, taken with the Advanced Camera for Surveys High Resolution Channel is the most detailed yet, and shows how the material from the star was not thrown out in a uniform manner, but forms a huge dumbbell shape.

Eta Carinae is not only interesting because of its past, but also because of its future. It is one of the closest stars to Earth that is likely to explode in a supernova in the relatively near future (though in astronomical timescales the “near future” could still be a million years away). When it does, expect an impressive view from Earth, far brighter still than its last outburst: SN 2006gy, the brightest supernova ever observed, came from a star of the same type.

This image consists of ultraviolet and visible light images from the High Resolution Channel of Hubble’s Advanced Camera for Surveys. The field of view is approximately 30 arcseconds across.
