Gorgeous cotton candy clouds show how Hubble processes space images
This stunning new image from the Hubble Space Telescope might look like cotton candy, but in fact it's part of a nebula in a next door galaxy. Located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way which is around 160,000 light-years away, this nebula consists of dust and gas that glows in different colors which indicate different physical processes at work. If you're curious about how Hubble produces such vivid and colorful images and whether the colors are real or not, it helps to understand how telescope cameras work. Unlike the camera on your phone, for example, Hubble doesn't just point at an object and snap an image. Instead, its instruments like the Wide Field Camera 3, which produced this image, take multiple observations of the same object using different filters. Recommended Videos Each filter restricts the light being observed to just particular wavelengths. In this case, five different filters were used, covering wavelengths that the human eye can see, called optical wavelengths, as well as some in the ultraviolet and infrared. With multiple observations of the same object at different wavelengths, each of which is in black and white, the observations can then be combined to create a single colored image, which you can see in full size below. 'When image-processing specialists combine raw filtered data into a multi-coloured image like this one, they assign a colour to each filter. Visible-light observations are typically matched to the colour that the filter allows through. Shorter wavelengths of light such as ultraviolet are usually coloured blue or purple, while longer wavelengths like infrared are typically coloured red,' Hubble scientists explain. 'This colour scheme closely represents reality while adding new information from the portions of the electromagnetic spectrum that humans cannot see.' The way that Hubble images are produced is similar to how the James Webb Space Telescope uses filters and combines these to create stunning pictures of otherwise invisible objects, a process which requires both scientific knowledge and a degree of artistic flair from the image processors.

Hubble Telescope spies star-forming cocoons in neighboring galaxy (photo)

Young stars enveloped in a transformative cocoon of gas shine brightly in a new image from the Hubble Space Telescope. The newborn stars belong to a cluster known as NGC 460, which is located in a region of the Small Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. NGC 460 is surrounded by a number of other young stellar clusters and varying sized nebulae, which are clouds of gas and dust that fuel new star formation. Within this region, also known as N83, there are a number of O-type stars, the brightest, hottest and most massive of main-sequence stars (like the sun), which burn hydrogen at their core. O-type stars are rare; there are thought to be just 20,000 of them in the Milky Way, according to a statement from NASA releasing the Hubble image on March 8. "The clouds of gas and dust can give rise to stars as portions of them collapse, and radiation and stellar winds from those hot, young bright stars in turn shape and compress the clouds, triggering new waves of star formation," NASA officials said in the statement. "The hydrogen clouds are ionized by the radiation of nearby stars, causing them to glow." Related: The best Hubble Space Telescope images of all time! Classified as an open star cluster, NGC 460 is a loosely bound group of stars, held together by gravity. This type of cluster typically contains a few dozen to a few thousand relatively young stars from the same giant molecular cloud. In this case, NGC 460 is believed to have formed following a collision between two hydrogen clouds. This type of interaction could have triggered the birth of several O-type stars and nebulae in the N83 region, according to the statement. "The NGC 460 star cluster resides in one of the youngest parts of this interconnected complex of stellar clusters and nebulae," NASA officials said in the statement.

As one of the Milky Way's closest and brightest galactic neighbors, residing only about 200,000 light-years from Earth, the Small Magellanic Cloud offers an opportunity to study phenomena that are otherwise difficult to examine in more distant galaxies. The recent images of NGC 460 stem from a study on the gas and dust between stars — called the interstellar medium — to better understand how gravitational forces between interacting galaxies can foster bursts of star formation. Six overlapping observations taken using the Hubble Space Telescope at both visible and infrared wavelengths were combined to create the new mosaic image.

Fast-moving stars reveal supermassive black hole inside nearby galaxy
By Will Dunham WASHINGTON (Reuters) - The Large Magellanic Cloud is a dwarf galaxy residing near our Milky Way, visible to the naked eye as a luminous patch of light from Earth's southern hemisphere and named after Portuguese explorer Ferdinand Magellan, who observed it five centuries ago. New research is now providing a fuller understanding of the makeup of our galactic neighbor. A study based on the trajectory of nine fast-moving stars observed at the fringes of the Milky Way provides strong evidence for the existence of a supermassive black hole inside the Large Magellanic Cloud. Most galaxies are thought to have such a black hole at their core, but this represents the first evidence for one within the Large Magellanic Cloud. See for yourself — The Yodel is the go-to source for daily news, entertainment and feel-good stories. By signing up, you agree to our Terms and Privacy Policy. According to the researchers, data on the trajectory of these stars indicates they were flung out of the Large Magellanic Cloud after a violent close encounter with this black hole. Black holes are exceptionally dense objects with gravity so strong that not even light can escape. The Large Magellanic Cloud is located about 160,000 light-years from Earth, making it among the closest galaxies to the Milky Way. That makes this the nearest supermassive black hole to us aside from the one called Sagittarius A*, or Sgr A*, situated at the heart of the Milky Way. Sgr A* is about 26,000 light-years from Earth. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Just as the Milky Way is much more massive than the Large Magellanic Cloud, Sgr A* is much more massive than the newly identified black hole, which is among the least massive of any supermassive black holes known. Sgr A* has a mass roughly 4 million times greater than the sun's. This one has a mass about 600,000 times greater than the sun's. Sgr A*, in turn, is dwarfed by some supermassive black holes detected in other large galaxies such as one with a mass 6.5 billion times greater than that of the sun in a galaxy called Messier 87. That one and Sgr A* are the only two black holes ever imaged by astronomers. The new study focused on a class of stars called hypervelocity stars. They are produced when a binary star system - two stars gravitationally bound to each other - ventures too close to a supermassive black hole. "The intense gravitational forces tear the pair apart. One star is captured into a tight orbit around the black hole, while the other is flung outward at extreme velocities - often exceeding thousands of kilometers per second - becoming a hypervelocity star," said Jesse Han, a doctoral student in astrophysics at Harvard University and lead author of the study being published in the Astrophysical Journal and made public on Thursday. The sun travels through space at about 450,000 miles per hour (720,000 kph) while hypervelocity stars do so at several times that speed. The researchers used data from the European Space Agency's Gaia space observatory that has tracked more than a billion stars in our galaxy with unprecedented precision. There are 21 known hypervelocity stars in the Milky Way. Astronomers have confidently identified the origins of 16 of them, tracking seven of them back to Sgr A* at our galaxy's core and the other nine back to the Large Magellanic Cloud. "The only plausible explanation is that the Large Magellanic Cloud harbors a supermassive black hole in its center as well, analogous to Sgr A* in our galaxy," Han said. "The Large Magellanic Cloud, given its mass and structure, is totally expected to have a supermassive black hole of this mass. We just needed to find the evidence for it," Han said. "It's fun and exciting, but also something that really does make sense." Until now, the closest known supermassive black hole from beyond the Milky Way was the one inside the Andromeda galaxy, about 2.5 million light-years from Earth. It is the nearest major galaxy to the Milky Way. "The Large Magellanic Cloud is one of the best-studied galaxies, yet this supermassive black hole's existence was only inferred indirectly by tracing the origins of fast-moving stars. We have more work to do to actually pinpoint the location of the black hole," said Caltech astronomer and study co-author Kareem El-Badry.
