This video is unsettlingly relaxing. So, yes, kick back and #relax with one of the largest #explosions in our #solar system.

Well we are not the only planet that can have H2O keep that in mind I believe what you said BUT NASA has highly tranid professionals and even asteroids carry H2O

there is also a 25th anniversary ebook you can download in the post.
 
Take a flight to the Star Cluster Westerlund 2
APRIL 23, 2015: NASA and ESA are celebrating the Hubble Space Telescope's silver anniversary of 25 years in space by unveiling some of nature's own fireworks — a giant cluster of about 3,000 stars called Westerlund 2. The cluster resides inside a vibrant stellar breeding ground known as Gum 29, located 20,000 light-years away in the constellation Carina. The comparatively young, 2-million-year-old star cluster contains some of our galaxy's hottest, brightest, and most massive stars. The largest stars are unleashing a torrent of ultraviolet light and hurricane-force winds that etch away the enveloping hydrogen gas cloud. This creates a fantasy celestial landscape of pillars, ridges, and valleys.

The annual Lyrid meteor shower is active each year from about April 16 to 25. In 2015, the peak of this shower – which tends to come in a burst and usually lasts for less than a day – will fall on the mornings of April 22 or 23, with the nod going to the later date. The greatest number of meteors should fall during the few hours before dawn on either date.

As Hubble celebrates 25 years, a quick look at the WFPC2 (Wide Field and Planetary Camera 2) and COSTAR (Corrective Optics Space Telescope Axial Replacement) which initially corrected for the spherical aberration of the main mirror, back in 1993.

A fascinating look at the methods and techniques used to find out if there's intelligent/structured information in a signal. *More details in the original post below... 
Enjoy!
 
Among the chaos and noise of signals of all kinds from space, how can SETI eek out and identify signals containing information from an intelligent source?
Earlier today, I posted a 16 part series on Information Theory. This video is the last part, and to me, the most fascinating.

"How can we know if such a signal is coming from an intelligent source? At the first SETI meeting in 1961, John Lilly proposed that researchers study Dolphin languages to help them learn more about what extraterrestrial signals might be like. Much of this early work culminated in the research by Lawrence R Doyle and Brenda McCowan. Doyle and McCowan's work is based on the assumption that if there is some common trait in both human and non-human communication systems, then extraterrestrial communication systems should also share this trait." 

This 10 minute video explores these studies and techniques used to find out if a signal contains information from an intelligent source.

"European Southern Observatory's MUSE telescope instrument created [this] 3D view of the iconic Pillars of Creation in the Eagle Nebula, or Messier 16."

"...The new MUSE data has allowed astronomers to measure the rate at which the Pillars of Creation are being destroyed [...]: they lose about 70 times the mass of the sun every million years...”

There is a good bit on orbital mechanics and rendezvous with the ISS in here.  It isn't as straight forward as a lot of people think it is.

Well it's just rockets aren't robust when you try to make em cheap. They operate very close to the limits of materials (not fuels unfortunately yet). and have to fly in a chosen dynamic range that won't destroy them. Now if money was limitless and you wanted reuse ability you would burn fuel around the rocket to provide a ablative plasma layer going Mach 10 at 120,000 ft. Then pulse detonate to Mach 22 into orbit, carrying enormous payloads. Just saying we do the same things over and over because alternatives are not yet fully modeled enough to be sure next gen stuff can do the job.

Earth: There's No Pace Like Home

I created this video last year for #EarthDay, but since #Hubble25  has been quickly approaching, I have not been able to create a new one. 

That being said, I still LOVE how this came out as a poignant reminder that this is our home and the only home we have for the time being. Let's do all we can to keep it viable for ourselves and the countless other species that inhabit it.

I like Earth seen from 30,000 kilometers and more. It's just that down here it's not so great for a huge majority of creatures trapped on its surface.
