Infant Star’s Artistic Outburst

The artistic outburst of an extremely young star, in the earliest phase of formation, is captured in this spectacular image from the NASA/ESA Hubble Space Telescope. The colourful 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 colourful object to the lower left, produced as the cooler material is heated by the jet (opo9524a, potw1307a).

This wispy object is known as HH34 and it is an example of a Herbig–Haro (HH) object. It resides approximately 1400 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 (heic1113).

Visible light emitted from a black hole has been detected for the first time

Got a decent telescope at home? That's all you need to observe a nearby black hole.

For the first time, astronomers have observed bursts of visible light being released by a black hole as it swallows matter from nearby stars.

These flashes of light, which lasted between several minutes to a few hours, were seen coming from a black hole in the Cygnus constellation, located about 7,800 light-years away from Earth. Incredibly, some of the flashes were so bright, the team says amateur astronomers could see them with a modest 20-cm telescope.

“We find that activity in the vicinity of a black hole can be observed in optical light at low luminosity for the first time,” astronomer and lead researcher, Mariko Kimura from Kyoto University in Japan, told Charles Q. Choi at Space.com.

“These findings suggest that we can study physical phenomena that occur in the vicinity of the black hole using moderate optical telescopes without high-spec X-ray or gamma-ray telescopes.”

Picture of the Day: Messier 9 Star Cluster

NASA’s Hubble Space Telescope has taken this incredible picture of Messier 9, a globular star cluster located near the center of our galaxy. The cluster, located some 25,000 light years away, is too faint to be seen with the naked eye, but Hubble has captured more than 250,000 individual stars there. Globular clusters are believed to have emerged when the galaxy was quite young, and the stars that make up Messier 9 are calculated to be around twice as old as our sun.

Are u really in space

Yes. Really. And now I am in space over New Orleans…and now I’m over Mobile, Alabama. 

Mars has flowing rivers of briny water, NASA satellite reveals

NASA just released the out-of-this-world news.

A recap of January in pictures! Winters the best time for astrophotography which is why I’ve had plenty of opportunities to get outside and capture the cosmos! 

All Quiet in the Nursery?

The dark patch snaking across this spectacular image of a field of stars in the constellation of Ophiuchus (The Serpent-bearer) is not quite what it appears to be.

Although it looks as if there are no stars here, they are hidden behind this dense cloud of dust that blocks out their light. This particular dark cloud is known as LDN 1768.

Despite their rather dull appearance, dark nebulae like LDN 1768 are of huge interest to astronomers, as it is here that new stars form. Inside these vast stellar nurseries there are protostars — stars at the earliest stage of their lives, still coalescing out of the gas and dust in the cloud.

Eventually, the protostars will become dense and hot enough to start the nuclear reactions that will produce visible light and they will start to shine. When this happens, they will blow away the cocoon of dust surrounding them and cause any remaining gas to emit light as well, creating the spectacular light show known as an HII region.

Using the advanced adaptive optics system on the Gemini South telescope, astronomers have imaged a beautiful stellar jewel-box – a tightly packed cluster of stars that is one of the few places in our galaxy where astronomers think stars can actually collide. Stellar collisions are important because they can provide the key to understand the origin of exotic objects that cannot be interpreted in terms of the passive evolution of single stars. read more here credit: Gemini Observatory/AURA
