Curiosities...

Potentially Habitable Moons

Explanation: For astrobiologists, these may be the four most tantalizing moons in our Solar System. Shown at the same scale, their exploration by interplanetary spacecraft has launched the idea that moons, not just planets, could have environments supporting life. The Galileo mission to Jupiter discovered Europa’s global subsurface ocean of liquid water and indications of Ganymede’s interior seas. At Saturn, the Cassini probe detected erupting fountains of water ice from Enceladus indicating warmer subsurface water on even that small moon, while finding surface lakes of frigid but still liquid hydrocarbons beneath the dense atmosphere of large moon Titan. Now looking beyond the Solar System, new research suggests that sizable exomoons, could actually outnumber exoplanets in stellar habitable zones. That would make moons the most common type of habitable world in the Universe.

This is actually a test showing how sponges pump water through themselves for filter feeding!
They simply colored the water around them so you could easily see the process :D

Sponges will never cease to fascinate me!

Aurora over Maine

Explanation: It has been a good week for auroras. Earlier this month active sunspot region 2158 rotated into view and unleashed a series of flares and plasma ejections into the Solar System during its journey across the Sun’s disk. In particular, a pair of Coronal Mass Ejections (CMEs) impacted the Earth’s magnetosphere toward the end of last week, creating the most intense geomagnetic storm so far this year. Although power outages were feared by some, the most dramatic effects of these impacting plasma clouds were auroras seen as far south as Wisconsin, USA. In the featured image taken last Friday night, rays and sheets of multicolored auroras were captured over Acadia National Park, in Maine, USA. Since another CME plasma cloud is currently approaching the Earth, tonight offers another good chance to see an impressive auroral display.

From NASA Administrator Charlie Bolden’s Blog : 
Today, with the selection of Boeing and SpaceX to be the first American companies to launch our astronauts to the International Space Station, NASA has set the stage for what promises to be the most ambitious and exciting chapter in the history of human space flight.
From day one, the Obama Administration has made it clear that the greatest nation on Earth should not be dependent on other nations to get into space. Thanks to the leadership of President Obama and the hard work of our NASA and industry teams, today we are one step closer to launching our astronauts from U.S. soil on American spacecraft and ending the nation’s sole reliance on Russia by 2017. Turning over low-Earth orbit transportation to private industry also will allow NASA to focus on an even more ambitious mission – sending humans to Mars.

Has anyone else noticed that when the title COSMOS appears on screen the first two letters to appear are the C and S?
It’s a tribute to Carl Sagan.

Bring home the Universe!

Introducing the new and official Hey there, Universe online store! (powered by Amazon)

I have went through the entirety of the science-“cosm” on Amazon and have hand-picked a select few items that are featured here. Most notably, I want to introduce my followers to a list of my favorite science books, most of which are considered “popular science”, but some are also good reads for beginners, as well as experts who are interested in topics from other subjects.

Along with the books—which have been categorized into “Astrobiology, Biology, Astronomy, Physics, Geology”—I have also picked out some of my favorite apparel items on Amazon as well as gifts, toys, decors, for all of us who want to bring home the universe. 

I will try to promote this shop as little as possible (potentially 2 or 3 times a week), not every other hour, so don’t fret! The shop is run by me but all the transactions will be handled through Amazon. Feel free to give me a feedback on the store, or if you’re interested in seeing any specific item in the list. 

Lastly, if you are a college student (it’s back-to-school time again!), I would definitely recommend getting Amazon Prime! I’m sure you’ve heard of it by now, you get FREE Two-Day Shipping for one year just for signing up for Amazon Student. Click here to sign up today!
