Like an illustration in a galactic Just So Story, the Elephaunt’s Trunk Nebula winds through the emission nebula and young star cluster complex IC 1396, in the high and far off constellation of Cepheus. Of course, the cosmic elephant’s trunk is over 20 light-years long. This composite was recorded through narrow band filters that transmit the light from ionized hydrogen, sulfur, and oxygen atoms in the region. The resulting image highlights the bright swept-back ridges that outline pockets of cool interstellar dust and gas. Such embedded, dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within the obscuring cosmic dust. Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees.

Hubble Gazes at Long-dead Star

NASA - Hubble Space Telescope patch.

July 29, 2016

External image

This NASA/ESA Hubble Space Telescope image captures the remnants of a long-dead star. These rippling wisps of ionized gas, named DEM L316A, are located some 160,000 light-years away within one of the Milky Way’s closest galactic neighbors — the Large Magellanic Cloud (LMC).

The explosion that formed DEM L316A was an example of an especially energetic and bright variety of supernova, known as a Type Ia. Such supernova events are thought to occur when a white dwarf star steals more material than it can handle from a nearby companion, and becomes unbalanced. The result is a spectacular release of energy in the form of a bright, violent explosion, which ejects the star’s outer layers into the surrounding space at immense speeds. As this expelled gas travels through the interstellar material, it heats up and ionizes it, producing the faint glow that Hubble’s Wide Field Camera 3 has captured here.

The LMC orbits the Milky Way as a satellite galaxy and is the fourth largest in our group of galaxies, the Local Group. DEM L316A is not the only supernova remnant in the LMC; Hubble came across another one in 2010 with SNR 0509, and in 2013 it snapped SNR 0519.

The Great Andromeda Galaxy

The Andromeda Galaxy, also known as Messier 31 or NGC 224, is a spiral galaxy that is approximately 2.5 million light-years away in the Andromeda constellation. The Andromeda Galaxy is the nearest spiral galaxy to our Milky Way galaxy, but not the nearest galaxy overall. The Andromeda Galaxy is also the largest galaxy of the Local Group, which also contains the Milky Way, the Triangulum Galaxy, and about 44 other smaller galaxies. Our Milky Way and the Andromeda are expected to collide in around 3.75 billion years, eventually merging to form a giant elliptical or large disk galaxy. The collision will not effect most matter in the galaxies, because space is so large most matter will only interact gravitationally. However, The Gas clouds of the the two galaxies will collide and begin to form new stars.

The next time you want to put a poem on your iffy Photoshop job of a galaxy or nebula, remember it took someone hours of editing just like this to make the original. It’s like salting your food at a Michelin restaurant. So, I dunno, at least make it some T.S. Eliot or something worth all that effort.

These “galaxy” tees from spiralukofficial are inexplicably named after planets (Pluto, Neptune, and Jupiter), but they are still pretty damn cool IMHO. Especially the first one, which is one of my all-time favorite space images: the Hubble Ultra Deep Field (HUDF).

Every single speck of light in the HUDF is a galaxy (save five stars) containing roughly 100 billion stars. There are a total of 10,000 galaxies in this one image which covers a patch of sky roughly equal to 1/50th area of the full moon. We have reason to believe this patch of sky is no different from any other patch of sky so imagine covering the entire sky with fields of 10,000 galaxies - that yields an estimate of 100 billion galaxies in the Universe! 

Now go buy this shirt and school all your friends with your newfound astronomy knowledge.

A Montage of the Carina Nebula

The Carina Nebula (known by astronomers as NGC 3372) is sometimes called the Great Nebula in Carina or the Grand Nebula. These images taken by the Hubble space telescope show the magnificent structure within the Carina Nebula. These images contain regions of dense star formation, interstellar winds, massive particle clouds and much more. Many of these structures are hundreds of light-years across and make the size of our solar system look pathetic in comparison. The Carine Nebula is about 10,000 light-years away from earth and is located in the constellation Carina.

We reblogged @staceythinx‘s @shenovafashion post, but finally we have our own to share - with designs inspired by some of our favorite images!

From top to bottom:

Butterfly Nebula (and Hubble eXtreme Field)

Jupiter (with a purple hue … read on to learn why!)

Spiral galaxy (I haven’t identified it yet - can anyone help?)

Orion nebula

And last but not least, PLUTO!!!

Holly from @shenovafashion told me the model, Gauri, is a double major in chemical engineering and philosophy who works at NASA as a research scientist and at an energy materials nanotechnology startup in Silicon Valley. Impressive!

The Shenova @etsy shop lists sizes XS-L, but @shenovafashion confirmed that she is working on larger sizes and is happy to take custom orders!

Finally, why is Jupiter purple? To represent what a cool brown dwarf might look like! Related: can you guess which dress is on its way to my house right now? Here’s a hint! ;)

Last three days to win a startorialist prize pack! We’re collaborating with science communication researcher Dr. Paige Brown Jarreau for a survey of startorialist readers. Your participation will help us improve STARtorialist, contribute to publishable research on the readers of science blogs, and enter you to win one of three STARtorialist prize packs (like we gave away earlier this year). The survey should only take you 10-15 minutes to complete. Take the survey here!

The Carina Nebula - A Birthplace Of Stars

The Carina Nebula lies at an estimated distance of 6,500 to 10,000 light years away from Earth in the constellation Carina. This nebula is one of the most well studied in astrophysics and has a high rate of star formation. The star-burst in the Carina region started around three million years ago when the nebula’s first generation of newborn stars condensed and ignited in the middle of a huge cloud of cold molecular hydrogen. Radiation from these stars carved out an expanding bubble of hot gas. The island-like clumps of dark clouds scattered across the nebula are nodules of dust and gas that are resisting being eaten away by photons (particles of light) that are ionizing the surrounding gas (giving it an electrical charge).

Many spiral galaxies have bars across their centers. Even our own Milky Way Galaxy is thought to have a modest central bar. Prominently barred spiral galaxy NGC 1073, pictured above, was captured in spectacular detail in this recently released image taken by the orbiting Hubble Space Telescope. Visible are dark filamentary dust lanes, young clusters of bright blue stars, red emission nebulas of glowing hydrogen gas, a long bright bar of stars across the center, and a bright active nucleus that likely houses a supermassive black hole. Light takes about 55 million years to reach us from NGC 1073, which spans about 80,000 light years across. NGC 1073 can be seen with a moderately-sized telescope toward the constellation of the Sea Monster (Cetus), Fortuitously, the above image not only caught the X-ray bright star system IXO 5, visible on the upper left and likely internal to the barred spiral, but three quasars far in the distance.

Centaurus A, the remains of a galaxy collision that happened 600 million years ago. 

The dark clouds are made up of compressed hydrogen that act as kind of interstellar nurseries, where new stars are born. These stars appear reddish pink in the first image. Stars rely on nuclear fusion to fuel them, essentially all that is is smashing hydrogen atoms together at high speeds to create helium atoms, releasing mountains of energy in the process, which can be seen as light. This fact makes these clouds of hydrogen the ideal place for new stars to develop.

At the centre lies a supermassive black hole which is 1 billion times more massive than our sun. It consumes all matter that strays too close and upon doing so, releases huge jets of energy, which can be seen in the second image.
