A Marvel of Galactic Morphology: NGC 1156 | Hubble

A Marvel of Galactic Morphology: NGC 1156 | Hubble

This galaxy has a shape unlike many of the galaxies familiar to Hubble. Its thousands of bright stars evoke a spiral galaxy, but it lacks the characteristic ‘winding’ structure. The shining red blossoms stand out as well, twisted by clouds of dust—these are the locations of intense star formation. Yet it also radiates a diffuse glow, much like an elliptical galaxy and its core of older, redder stars. This galactic marvel is known to astronomers as NGC 1156.

NGC 1156 is located around 25 million light-years from Earth, in the constellation Aries. It has a variety of different features that are of interest to astronomers. A dwarf irregular galaxy, it is also classified as isolated, meaning no other galaxies are nearby enough to influence its odd shape and continuing star formation. The extreme energy of freshly formed young stars gives color to the galaxy, against the red glow of ionized hydrogen gas, while its center is densely-packed with older generations of stars.

Hubble has captured NGC 1156 before—this new image features data from a galactic gap-filling program simply titled “Every Known Nearby Galaxy”. Astronomers noticed that only three quarters of the galaxies within just over 30 million light-years of Earth had been observed by Hubble in sufficient detail to study the makeup of the stars within them. They proposed that in between larger projects, Hubble could take snapshots of the remaining quarter—including NGC 1156. Gap-filling programs like this one ensure that the best use is made of Hubble’s valuable observing time.

Ghostly Reflections in The Pleiades | Hubble

Ghostly Reflections in The Pleiades | Hubble

The Hubble Space Telescope has caught the eerie, wispy tendrils of a dark interstellar cloud being destroyed by the passage of one of the brightest stars in the Pleiades star cluster. Like a flashlight beam shining off the wall of a cave, the star is reflecting light off the surface of pitch black clouds of cold gas laced with dust. These are called reflection nebulae.

This image shows a dark interstellar cloud ravaged by the passage of Merope, one of the brightest stars in the Pleiades star cluster. Just as a torch beam bounces off the wall of a cave, the star is reflecting light from the surface of pitch-black clouds of cold gas laced with dust. As the nebula approaches Merope, the strong starlight shining on the dust decelerates the dust particles. The nebula is drifting through the cluster at a relative speed of roughly 11 kilometers per second.

Tantrums of a Baby Star | Hubble

Tantrums of a Baby Star | Hubble

Herbig-Haro objects are some of the rarer sights in the night sky, taking the form of thin spindly jets of matter floating amongst the surrounding gas and stars. The two Herbig-Haro objects cataloged as HH46 and HH47, seen in this image taken with the NASA/European Space Agency Hubble Space Telescope, were spotted in the constellation of Vela (The Sails), at a distance of over 1,400 light-years from Earth. Prior to its discovery in 1977 by the American astronomer R. D. Schwartz, the exact mechanism by which these multi-colored objects formed was unknown.

Before 1997 it was theorized by Schwartz and others that the objects could be a type of reflection nebula, or a type of shock wave formed from the gas emitted from a star interacting with the surrounding matter. The mystery was finally solved when a protostar, unseen in this image, was discovered at the center of the long jets of matter. The outflows of matter, some 10 light-years across, were ejected from the newly born star and violently propelled outwards at speeds of over 150 kilometers per second. Upon reaching the surrounding gas, the collision created the bright shock waves seen here.

Hubble Snaps a Jet Set

Hubble Snaps a Jet Set

An energetic outburst from an infant star streaks across this image from the NASA/European Space Agency Hubble Space Telescope. This stellar tantrum—produced by an extremely young star in the earliest phase of formation —consists of an incandescent jet of gas travelling at supersonic speeds. As the jet collides with material surrounding the still-forming star, the shock heats this material and causes it to glow. The result is the colorfully wispy structures, which astronomers refer to as Herbig–Haro objects, billowing across the lower left of this image.

Herbig–Haro objects are seen to evolve and change significantly over just a few years. This particular object, called HH34, was previously captured by Hubble between 1994 and 2007, and again in glorious detail in 2015. HH34 resides approximately 1,250 light-years from Earth in the Orion Nebula, a large region of star formation visible to the unaided eye. The Orion Nebula is one of the closest sites of widespread star formation to Earth, and as such has been pored over by astronomers in search of insights into how stars and planetary systems are born.

The data in this image are from a set of Hubble observations of four nearby bright jets with the Wide Field Camera 3 taken to help pave the way for future science with the NASA/ESA/CSA James Webb Space Telescope. Webb—which will observe at predominantly infrared wavelengths—will be able to peer into the dusty envelopes surrounding still-forming protostars, revolutionizing the study of jets from these young stars. Hubble’s high-resolution images of HH34 and other jets will help astronomers interpret future observations with Webb.

Infant Star’s Artistic Outburst | Hubble

Infant Star’s Artistic Outburst | Hubble

The artistic outburst of an extremely young star, in the earliest phase of formation, is captured in this spectacular image from the NASA/European Space Agency Hubble Space Telescope. The colorful wisps, found in the lower left of the image, are painted onto the sky by a young star cocooned in the partially illuminated cloud of obscuring dust seen to the upper right.

Pictured punching through the enshrouding dust is an extremely hot, blue jet of gas released by the young star. As this jet speeds through space, it collides with cooler surrounding material. The result is the colorful object to the lower left, produced as the cooler material is heated by the jet.

This wispy object is known as HH34 and it is an example of a Herbig–Haro (HH) object. It resides approximately 1,400 light-years away near the Orion Nebula, a large star formation region within the Milky Way. HH objects exist for a cosmically brief time—typically thousands of years—with changes seen in observations taken only a few years apart.

Although the jet extends the entire length between the infant star and HH34, only a fraction of it appears visible. This part of the jet possesses an intricate structure of knots and ripples, thought to be caused by the different outbursts catching up and ramming into each other over time.

A Cosmic Lightsaber in 3D: Gas Jets from a Young Star in Orion | Hubble

This video envisions a three-dimensional perspective on the Herbig-Haro object as it is seen by the NASA/European Space Agency Hubble Space Telescope.

The sequence starts with a wide-field view covering the vast dark cloud of the Orion B molecular cloud complex and a scattering of stars. As the virtual camera flies into the dark nebula, the stars pass off-screen and the details of the forming stars and their red jets are revealed.

While the central star is hidden, its lightsaber-like jets peak out of the gas and dust. These jets have carved an hourglass-shaped cavity in the near side of the nebula.

The jet from another stellar newborn in this region has created a cylindrical tunnel through the gas extending to the left. Careful study of the Hubble data reveals a few other jets heating and displacing the gas and dust around them.

An Orbital Sunrise & Canadarm2 | International Space Station

An orbital sunrise begins illuminating Earth's atmosphere with the International Space Station's Canadarm2 robotic arm extending from the orbital lab as it soared 260 miles above the Pacific Ocean.

The Mobile Servicing System (MSS), is a robotic system on board the International Space Station (ISS). Launched to the ISS in 2001, it plays a key role in station assembly and maintenance; it moves equipment and supplies around the station, supports astronauts working in space, and services instruments and other payloads attached to the ISS and is used for external maintenance. Astronauts receive specialized training to enable them to perform these functions with the various systems of the MSS.

The MSS is composed of three components:

a) the Space Station Remote Manipulator System (SSRMS), known as Canadarm2.

b) the Mobile Remote Servicer Base System (MBS).

c) the Special Purpose Dexterous Manipulator (SPDM, also known as "Dextre").
