New images of Tarantula Nebula may help refine star formation theory

starnebula

NASA’s Hubble Space Telescope recently completed one of its most thorough and ambitious mozaic projectes. Astronomers at Hubble, stitched together some 438 separate images, both in visible and infra-red light, to complete the most accurate picture of the Tarantula Nebula so far, spanning across no less than 600 light-years. The Tarantula nebula contains some 800,000 newly born or developing stars,…

Universe at your fingertips – 3D prints of Hubble photos let the blind ‘see’

ngc-star-cluster-for-blind

Captioned above is one of Hubble‘s most famous and beautiful space photos. The photo features NGC 609 – a magnificent star cluster, which Hubble captured complete with colored gas, dust and a slew of stars of various brightness. Pictures like these remind people of the tremendous gift they have – sight. How can one share and hope to convey a…

This year Hubble will embark on one its most ambitious projects yet, as it’s scheduled to glimpse farther away into the Universe than ever before. Six new “deep field” images are slated, and recently astronomers at Hubble have delivered the first to the public. The image reveals extremely faint, tiny galaxies that may be more than 12 billion light-years away,…

The stars of the densest galaxy discovered thus far are 25 times closer than in Milky Way

This galaxy weighs more than 200 million suns, over half of which is concentrated within a radius of just 80 light years. (c) NASA/CXC/MSU/J.Strader et al, Optical: NASA/STScI

Using NASA’s Hubble Space Telescope, followed by observations done with NASA’s Chandra X-ray Observatory and ground-based optical telescopes, astronomers have identified what’s considered to be the densest galaxy found so far in the nearby part of the Universe. Classed as an  “ultra-compact dwarf galaxy” and dubbed as M60-UCD1, the density of stars in the galaxy is about 15,000 greater than  that found in Earth’s neighborhood…

Farthest supernova discovered by Hubble helps unravel Universe secrets

NASA and ESA

Astronomers using NASA’s Hubble Space Telescope have come across the farthest supernova of its type found thus far - a type Ia supernova which exploded some 10 billion years ago. The discovery isn’t just about setting milestones, however. Supernovae act as beacons that help astronomers measure the expansion of the Universe, and this latest finding will help deepen our understanding, especially concerning…

Hubble takes brilliant picture of young star population in elderly company

Click the pic for full size.

The great pics from Hubble just never end! This time, the brave telescope offered an impressive view of the center of globular cluster NGC 6362. The image of this spherical collection of stars takes a deeper look at the core of the globular cluster, which contains a high concentration of stars with different colors. Seeing what appears to be young…

Keep your children close – zombie planet roams once more

The general consensus was that a star called Fomalhaut doesn’t host any planet. But astronomers, the thorough people they are, decided to take another look at it using the Hubble Space Telescope – and the results contradicted the everything, claiming that Fomalhaut does in fact have a planet, and furthermore, this planet (Fomalhaut b) is a unique object, completely shrouded…

Universe expansion speed measured better than ever

universe expanding

The universe is expanding – fast. Researchers had a pretty good idea how fast, but now, they measured in even greater detail: it is expanding at a rate of 74.3 plus or minus 2.1 kilometers (46.2 plus or minus 1.3 miles) per second per megaparsec (a megaparsec being about 3 million light-years). Hard to wrap your head around it? Don’t…

Faint galaxy sheds light on the dawn of the Universe – many more to be found

old galaxy

The first galaxies formed very fast after the Big Bang – in cosmic time, that is. It’s estimated that the earliest ones appeared some 500 million years after the Big Bang, a period about which researchers know very little. How they observed it Even though they are typically very bright, such galaxies are quite hard to observe because they are…

Quasars “snack” regularly, instead of “feasting in one gulp”

Quasar Faint Light

Quasars are some of the brightest objects in the Universe. Their formed after black holes devour captured material, like  gas dust and stars that come too close, and release bright light that can be seen across the universe. Most of the popular astronomy today is orientated towards the particularly extremely bright quasars; those formed in a singular event consisting of the merger…
