The signs in space
  • Aries:Doing some no gravity parkour
  • Taurus:Getting a tan literally right next to the sun
  • Gemini:Just floating through space and time, nothing out of the ordinary
  • Cancer:Somehow found a way to make it to the death star
  • Leo:Riding a space rover on the moon
  • Virgo:Relaxing on the ISS
  • Libra:Became the queen of an alien planet
  • Scorpio:Got caught in a meteor shower
  • Sagittarius:Taking space selfies.....that is if they get reception from up there
  • Capricorn:Tries to spot where they live from thousands of kilometres above
  • Aquarius:Has seen too many movies about problems in space and they think any second their oxygen tank will brake
  • Pisces:Looking for their toothbrush that floated away

This is the NASA/ESA Hubble Space Telescope’s astonishing view of a dwarf galaxy known as NGC 1140, which lies 60 million light-years away. It has an irregular form because it’s undergoing what is known as a starburst. Despite being almost ten times smaller than the Milky Way it is creating stars at about the same rate, with the equivalent of one star the size of the Sun being created per year. This is clearly visible in the image, which shows the galaxy illuminated by bright, blue-white, young stars.

Galaxies like NGC 1140 — containing large amounts of primordial gas with way fewer elements heavier than hydrogen and helium than present in our Sun — are of particular interest to astronomers. Their composition makes them similar to the intensely star-forming galaxies in the early Universe. And these early Universe galaxies were the building blocks of present-day large galaxies like our galaxy, the Milky Way. But, as they are so far away these early Universe galaxies are harder to study so these closer starbursting galaxies are a good substitute for learning more about galaxy evolution.

NASA Astronomy Picture of the Day 2015 July 29 

The Deep Lagoon 

Ridges of glowing interstellar gas and dark dust clouds inhabit the turbulent, cosmic depths of the Lagoon Nebula. Also known as M8, the bright star forming region is about 5,000 light-years distant. But it still makes for a popular stop on telescopic tours of the constellation Sagittarius, toward the center of our Milky Way Galaxy. Dominated by the telltale red emission of ionized hydrogen atoms recombining with stripped electrons, this stunning, deep view of the Lagoon’s central reaches is about 40 light-years across. Near the center of the frame, the bright hourglass shape is gas ionized and sculpted by energetic radiation and extreme stellar winds from a massive young star.

The Signs When The World Ends

Aries: FUCK THIS SHIT, THIS AINT FAIR
Taurus: Dammit, I didn’t loose my virginity yet…
Gemini: (sleeps through it)
Cancer: (wont stop screaming)
Virgo: Why does this have to be happening today? This is the one day where my hair looks good, fml.
Leo: NOOO!! MY FOLLOWERS!! MY MUSIC!!!
Libra: Blogging/on tumblr as it happens
Scorpio: Finally
Sagittarius: There was so much more I wanted to do!
Aquarius: Haha bitches, I predicted this would happen and you didn’t listen. Now die… Slowly….painfully.
Pisces: (listening to music and doesn’t realize what’s going on)

On July 29, 1958, President Eisenhower signed the National Aeronautics & Space Act.

On July 29th, 1958, less than a year after Sputnik 1 was launched into orbit, President Eisenhower signed the National Aeronautics and Space Act establishing NASA as a civilian space agency. The new agency absorbed the National Advisory Committee for Aeronautics, including its budget, resources and personnel. Prior to the formation of NASA, space exploration was considered to be largely a military enterprise. NASA would begin operations on October 1, 1958.

Neutron star’s echoes

Circinus X-1 is a freak of the Milky Way. Located in the plane of the galaxy, Circinus X-1 is the glowing husk of a binary star system that exploded a mere 2,500 years ago. The system consists of a nebula and a neutron star, the incredibly dense collapsed core of the exploded star, still in the orbital embrace of its companion star.

The rings are light echoes from Circinus X-1’s X-ray burst. Each of the four rings indicates a dense cloud of dust between us and the supernova remnant. When X-rays encounter grains of dust in interstellar space they can be deflected, and if the dust clouds are dense they can scatter a noticeable fraction of the X-rays away from their original trajectory, putting them on a triangular path.
