Reflection Nebula NGC 1999: The Cosmic Keyhole | Schulman Telescope

Reflection Nebula NGC 1999: The Cosmic Keyhole | Schulman Telescope

NGC 1999 is a reflection nebula in the constellation Orion around 1,350 light-years from Earth. It is located near the Orion Nebula, the closest region of massive star formation to Earth. NGC 1999 itself is a relic of recent star formation—it is composed of detritus left over from the formation of a newborn star. The most notable aspect of NGC 1999’s appearance, however, is the conspicuous hole in its center, which resembles an inky-black keyhole of cosmic proportions.

Just like fog curling around a street lamp, reflection nebulae like NGC 1999 only shine because of the light from an embedded source. In the case of NGC 1999, this source is the newborn star V380 Orionis, visible at the center of this image.

Spiral Galaxy NGC 6951 in Cepheus | Hubble

Spiral Galaxy NGC 6951 in Cepheus | Hubble

Bright blue spiral arms twist around the bright-white center of this starry galaxy. This new Hubble Space Telescope image features NGC 6951, an intermediate spiral galaxy 78 million light-years away in the Cepheus constellation. Discovered independently by French astronomer Jerome Coggia in 1877 and American astronomer Lewis Swift in 1878, NGC 6951 intrigues scientists with its stellar history. The galaxy had its highest rates of star formation about 800 million years ago, then sat quietly for 300 million years before beginning to birth stars again. The average age of a star cluster, or gravitationally-bound group of stars, in this galaxy is 200 to 300 million years old, though are stars as old as one billion years. Turbulent regions of gas, shown in dark red, surround the bright blue pinpricks that are star clusters.

Astronomers often classify NGC 6951 as a Type II Seyfert galaxy, a type of active galaxy that emits large amounts of infrared radiation and has slow-moving gaseous matter near its center. Astronomers classify NGC 6951 as a low-ionization nuclear emission-line region (LINER) galaxy, which is similar to a Type II Seyfert galaxy but with a cooler nucleus that emits weakly ionized or neutral atoms like oxygen, nitrogen, and sulfur. The whole galaxy is about 75,000 light-years across, and since it is close to the northern celestial pole, it is visible from the northern hemisphere.

At the center of NGC 6951 lies a supermassive black hole surrounded by a ring of stars, gas, and dust about 3,700 light-years across. This “circumnuclear ring” is between 1 and 1.5 billion years old and has been forming stars for most of that time. Scientists hypothesize that interstellar gas flows through the dense, starry bar of the galaxy to the circumnuclear ring, which supplies new material for star formation. Up to 40 percent of the mass in the ring comes from relatively new stars that are less than 100 million years old. Spiral lanes of dust, shown in dark orange, connect the center of the galaxy to its outer regions, contributing more material for future star formation.

Stars in NGC 6951 have also experienced terrific stellar explosions known as supernovae; astronomers have counted as many as six supernovae in this galaxy in the past 25 years. Scientists continue to study NGC 6951 to better understand the environments that produce supernovae. Studying the emissions from supernovae helps astronomers understand the progenitor star, its age, luminosity, and position.

Star Cluster NGC 7380 in The Wizard Nebula | Schulman Telescope

Star Cluster NGC 7380 in The Wizard Nebula | Schulman Telescope

NGC 7380 is a young open cluster of stars in the northern circumpolar constellation of Cepheus, discovered by Caroline Herschel in 1787. The surrounding emission nebulosity is known colloquially as the Wizard Nebula, which spans an angle of 25′. German-born astronomer William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77.

A Vibrant Virgo Cluster Galaxy: NGC 4654 | Hubble

A Vibrant Virgo Cluster Galaxy: NGC 4654 | Hubble

A bright spiral galaxy fills the frame from the lower-right to the upper-left. The galaxy is tilted toward us and holds bright blue-white stars and reddish-brown dust lanes that showcase its spiral nature.

It is easy to get swept up in the swirling starry arms of this intermediate spiral galaxy, NGC 4654, in the constellation Virgo. The galaxy has a bright center and is labeled “intermediate” because it has characteristics of both unbarred and barred spirals. NGC 4654 is just north of the celestial equator, making it visible from the northern hemisphere and most of the southern hemisphere. The galaxy is around 55 million light-years from Earth.

NGC 4654 is one of many Virgo Cluster galaxies that have an asymmetric distribution of stars and of neutral hydrogen gas. Astronomers reason that NGC 4654 may be experiencing a process called “ram pressure stripping,” where the gravitational pull of the Virgo galaxy cluster puts pressure on NGC 4654 as it moves through a superheated plasma made largely of hydrogen called the “intracluster medium.” This pressure feels like a gust of wind—think of a biker feeling wind even on a still day—that strips NGC 4654 of its gas. This process produced a long, thin tail of hydrogen gas on the galaxy’s southeastern side. Most galaxies that experienced ram pressure stripping hold very little cold gas, halting the galaxy’s ability to form new stars, since stars generate from dense gas. However, NGC 4654 has star formation rates consistent with other galaxies of its size.

NGC 4654 also had an interaction with the companion galaxy NGC 4639 about 500 million years ago. The gravity of NGC 4639 stripped NGC 4654’s gas along its edge, limiting star formation in that region and causing the asymmetrical distribution of the galaxy’s stars.

Scientists study galaxies like NGC 4654 to examine the connection between young stars and the cold gas from which they form. NASA's Hubble Space Telescope took this image in visible, ultraviolet, and infrared light.

The Hourglass Nebula (MyCn18) in Musca | Hubble

The Hourglass Nebula (MyCn18) in Musca | Hubble

Do you see the hourglass shape—or does it see you?

These are images of MyCn18, a young planetary nebula located in the Milky Way Galaxy. It is about 8,000 light-years away. The image was taken with the Wide Field and Planetary Camera 2 (WFPC2) aboard the Hubble Space Telescope (HST).

The true shape of MyCn18 is an hourglass with an intricate pattern of 'etchings' in its walls. This picture has been composed from three separate images taken in the light of ionized nitrogen (represented by red), hydrogen (green), and doubly-ionized oxygen (blue). With its nuclear fuel exhausted, this brief, spectacular, closing phase of a Sun-like star's life occurs as its outer layers are ejected—its core becoming a cooling, fading white dwarf.

The results are of great interest because they shed new light on the poorly understood ejection of stellar matter which accompanies the slow death of Sun-like stars. In previous ground-based images, MyCn18 appears to be a pair of large outer rings with a smaller central one, but the fine details cannot be seen.

Rare Radio Galaxy NGC 612 in Sculptor | Hubble

Rare Radio Galaxy NGC 612 in Sculptor | Hubble

A striking orange and blue streak fills this new image from the Hubble Space Telescope. Hubble’s visible and infrared capabilities captured this edge-on view of lenticular galaxy NGC 612. It is about 400 million light-years from Earth and has a mass of around 1.1 trillion times that of our Sun.

Lenticular galaxies have a central bulge and disk much like spiral galaxies, but they lack the characteristic arms. They typically have older star populations and little ongoing star formation. 

In NGC 612, dust and cool hydrogen gas make up the majority of the galactic disc, the plane of matter we see in orange and dark red. This galaxy appears in the Sculptor constellation and is easily visible from Earth’s southern hemisphere.

NGC 612 is an active galaxy, which means that its center appears more than 100 times brighter than the combined light of its stars. It is also a Seyfert galaxy, the most common type of active galaxy. Seyfert galaxies emit large amounts of infrared radiation despite looking normal in visible light. NGC 612 is a Type II Seyfert, which means matter near the center of the galaxy moves rather calmly around the nucleus. The stars in this galaxy are unusually young, with ages around 40 to 100 million years.

NGC 612 is also an extremely rare example of a non-elliptical radio galaxy, a type of galaxy that shows significant radio emissions – in this case, an association with radio source PKS 0131-36. Astronomers have only discovered five such radio-emitting lenticular galaxies in the universe. One theory attributes NGC 612’s unusual radio emissions to a past interaction with a companion spiral galaxy. Another theory focuses on the galaxy’s bright and dominant bulge, which is similar to those seen in elliptical radio galaxies. By imaging this galaxy, astronomers hope to uncover more about what causes galaxies to emit radio waves.

British astronomer John Herschel discovered NGC 612 in 1837.

Never-Before-Seen Way to Annihilate a Star | NOIRLab

Cosmoview Episode 71: This artist's impression illustrates how astronomers studying a powerful gamma-ray burst (GRB) with the Gemini South telescope, operated by the National Science Foundation’s NOIRLab, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy.

Astrophotographer Role Bigler: "Even with strong light pollution, the polar light is very well visible . . ."

On Earth, auroras are mainly created by particles originally emitted by the Sun in the form of solar wind. When this stream of electrically charged particles gets close to our planet, it interacts with the magnetic field, which acts as a gigantic shield. While it protects Earth’s environment from solar wind particles, it can also trap a small fraction of them. Particles trapped within the magnetosphere—the region of space surrounding Earth in which charged particles are affected by its magnetic field—can be energized and then follow the magnetic field lines down to the magnetic poles. There, they interact with oxygen and nitrogen atoms in the upper layers of the atmosphere, creating the flickering, colorful lights visible in the polar regions here on Earth.

Earth auroras have different names depending on which pole they occur at. Aurora Borealis, or the northern lights, is the name given to auroras around the north pole and Aurora Australis, or the southern lights, is the name given for auroras around the south pole.
