Στο instagram της NASA συμβαίνει κάτι μαγικό

Αν ενθουσιάζεσαι με το διάστημα και τους αστερισμούς, αυτό είναι το προφίλ που πρέπει να ακολουθήσεις.

Μέχρι πριν λίγες μέρες δε γνώριζα καν την ύπαρξη αυτού του προφίλ στο instagram, και ενδιαφέρθηκα να το μάθω όταν η απάντηση στην ερώτηση "τι είναι αυτό;", ήταν "η NASA ανεβάζει κάτι αστερισμούς που μοιάζουν με μελιτζάνες, είναι τέλειο".

Και μετά μπήκα και ακολούθησα το προφίλ αυτό. Και ήταν όντως τέλειο.

Αν τρελαίνεσαι κι εσύ με τα αστέρια, το άγνωστο του σύμπαντος, τους πλανήτες και τους γαλαξίες, θα μαγευτείς μπαίνοντας σε αυτό το προφίλ. Εξίσου φοβερά είναι και τα βιντεάκια που δείχνουν τις απογειώσεις πυραύλων στιγμή προς στιγμή και το ταξίδι τους μέχρι να μπουν σε τροχιά. Για να μη μπω στη διαδικασία να σου μιλήσω για όλα τα φανταστικά πράγματα που κάνει η NASA και μπορείς να δεις στο instagram τους, πάρε μια γεύση παρακάτω και ακολούθησέ τους για περισσότερη εξωγήινη μαγεία.

Look up! Make plans now to stay up late or set the alarm tonight, the night of Aug. 11-12, to see a cosmic display of "shooting stars" light up the night sky. Known for its fast and bright meteors, the annual Perseid meteor shower is anticipated to be one of the best potential meteor viewing opportunities this year. The best way to see the Perseids is to go outside between midnight and dawn on the morning of Aug. 12. Allow about 45 minutes for your eyes to adjust to the dark. Lie on your back and look straight up. Increased activity may also be seen on Aug. 12-13. An outburst of Perseid meteors lights up the sky in August 2009 in this time-lapse image. Stargazers expect a similar outburst during next week's Perseid meteor shower, which will be visible tonight!

Peer into the vibrant core of a starburst galaxy, where new stars are forming & springing to life. This galaxy, spotted by the Hubble Space Telescope, is located approximately 50 million light-years away from Earth. Spanning 15,000 light-years, the galaxy displays massive and violent bursts of star formation, as shown by the hot, young, and blue stars scattered throughout the galaxy's rose-tinted core. Despite their appearance, the fuzzy white blobs dotted around the edge of this galaxy are not stars, but globular clusters. Found within a galaxy's halo, globular clusters are ancient collections of hundreds of thousands of stars. They orbit around galactic centers like satellites - the Milky Way, for example, hosts over 150 of them.

Like cosmic ballet dancers, the stars of the Pleiades cluster are spinning. But these celestial dancers are all twirling at different speeds. Astronomers have long wondered what determines the rotation rates of these stars. By watching these stellar dancers, our Kepler space telescope during its K2 mission has helped amass the most complete catalog of rotation periods for stars in a cluster. This information can help astronomers gain insight into where and how planets form around these stars, and how such stars evolve. This image shows the Pleiades cluster of stars as seen through the eyes of WISE, or our Wide-field Infrared Survey Explorer.

Spinning a web into a giant red spider nebula: Huge waves are sculpted in this two-lobed nebula called the Red Spider Nebula, located some 3,000 light-years away in the constellation of Sagittarius. This warm planetary nebula harbors one of the hottest stars known and its powerful stellar winds generate waves 100 billion kilometers (62.4 billion miles) high. The waves are caused by supersonic shocks, formed when the local gas is compressed and heated in front of the rapidly expanding lobes. The atoms caught in the shock emit the spectacular radiation seen in this image.

The phenomenon of pareidolia is when people see familiar shapes in images. This galaxy cluster has invoked the nickname of the "Toothbrush Cluster" because of its resemblance to the dental tool. In fact, the stem of the brush is due to radio waves (green) while the diffuse emission where the toothpaste would go is produced by X-rays observed by Chandra (purple). Visible light data from the Subaru telescope show galaxies and stars (white) and a map from gravitational lensing (blue) shows the concentration of the mass, which is mostly (about 80%) dark matter.
