Magellanic gemstone in the southern sky [NGC 290]
Hubble has captured the most detailed image to date of the open star cluster NGC 290 in the Small Magellanic Cloud.
The image taken with the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope show a myriad of stars in crystal clear detail. The brilliant open star cluster, NGC 290, is located about 200,000 light-years away and is roughly 65 light-years across.

Alien Smog: How Pollution Could Help Locate E.T.

In the search for life beyond Earth, astronomers should look for signs of pollution in the atmospheres of alien planets outside the Earth’s solar system, a new study says.
The next-generation James Webb Space Telescope, which is set to launch in 2018, could hunt for worlds harboring alien life by sniffing their atmospheres for chlorofluorocarbons (CFCs), greenhouse gases that destroy ozone in the Earth’s atmosphere. These chemicals could be detected on planets with atmospheres that are 10 times thicker than Earth’s, the researchers said.
Scientists already scan the atmospheres of alien worlds for traces of oxygen and methane, gases that typically coexist in the presence of life. But searching for signs of pollution elsewhere in the universe could yield clues about more-advanced alien civilizations, the researchers said.
Of course, to very advanced civilizations, Earth’s own greenhouse gases might signal a primitive world, the scientists said.
"We consider industrial pollution as a sign of intelligent life, but perhaps civilizations more advanced than us, with their own SETI programs, will consider pollution as a sign of unintelligent life since it’s not smart to contaminate your own air," study leader Henry Lin, a student at Harvard University, said in a statement.

"Maybe we’re on Mars because of the magnificent science that can be done there - the gates of the wonder world are opening in our time. Maybe we’re on Mars because we have to be, because there’s a deep nomadic impulse built into us by the evolutionary process, we come after all, from hunter gatherers, and for 99.9% of our tenure on Earth we’ve been wanderers. And, the next place to wander to, is Mars. But whatever the reason you’re on Mars is, I’m glad you’re there. And I wish I was with you.”

Can I just say that I love, really love this blog? It's so beautiful and it really awakens the little scientist inside of me. :3

YASSSS! That’s what we like to hear. Thank you for reading and feel free to drop in the inbox anytime.

Many people object to “wasting money in space” yet have no idea how much is actually spent on space exploration. The CSA’s budget, for instance, is less than the amount Canadians spend on Halloween candy every year, and most of it goes toward things like developing telecommunications satellites and radar systems to provide data for weather and air quality forecasts, environmental monitoring and climate change studies. Similarly, NASA’s budget is not spent in space but right here on Earth, where it’s invested in American businesses and universities, and where it also pays dividends, creating new jobs, new technologies and even whole new industries.

Spiral galaxy NGC 4911 in the Coma Cluster

A long-exposure Hubble Space Telescope image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light-years away in the northern constellation Coma Berenices.

The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its centre. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. Hubble has also captured the outer spiral arms of NGC 4911, along with thousands of other galaxies of varying sizes. The high resolution of Hubble’s cameras, paired with considerably long exposures, made it possible to observe these faint details.

NGC 4911 and other spirals near the centre of the cluster are being transformed by the gravitational tug of their neighbours. In the case of NGC 4911, wispy arcs of the galaxy’s outer spiral arms are being pulled and distorted by forces from a companion galaxy (NGC 4911A), to the upper right. The resultant stripped material will eventually be dispersed throughout the core of the Coma Cluster, where it will fuel the intergalactic populations of stars and star clusters.

what are some good physics/space oriented popular science documentaries? I’ve watched Cosmos (both), Through The Wormhole and BBC’s Wonders and basically anything goes from modern physics and astronomy to classical physics and history of physics. Thank

into the universe with stephen hawking (2010), Voyage to the Planets (2004), the universe (2007), stephen hawking’s universe (1997), how the universe works (2010) :DD
