See the small, blue dot near the center of this image? That's the Curiosity rover as seen from the skies of Mars! This stunning shot of the car-sized rover traversing the rocky terrain of Mount Sharp was taken by a camera aboard NASA's Mars Reconnaissance Orbiter (MRO) on 5 June 2017, two months before the fifth anniversary of Curiosity's landing on the Red Planet in August of 2012. Using the most powerful telescope ever sent to Mars, the High Resolution Imaging Science Experiment (HiRISE) camera, MRO captured this image of Curiosity in the middle of its investigation of active sand dunes and the “Vera Rubin Ridge,” an uphill location containing hematite (the mineral form of Iron(III) oxide) that the NASA team hopes to examine. The rover has driven over 16.94 kilometers (10.53 miles) since it touched down on the Martian surface, and this image serves as a reminder of our enduring quest for knowledge. Which planet or space object would you like to see a rover on next?

The Coma Cluster consists of approximately 1,000 galaxies spread over about two degrees on the sky-roughly the size of your thumb held at arm's length, and four times the size of the Sun and the Moon seen from Earth. Gravity binds the galaxies together into a cluster, known as a galaxy cluster. Unlike the gravitationally bound planets in our solar system, however, the galaxies do not orbit a central heavy object like the Sun and thus execute more complicated orbits To carry out his observations, Zwicky persuaded Caltech to build an 18-inch Schmidt telescope that could capture arge numbers of galaxies in a single wide-angle photograph. He used the instrument to make a survey of all the galaxies in the cluster and used measurements of the Doppler shift of their spectra to determine their velocities. He then applied the virial theorem. A straightforward application of classical mechanics, the virial theorem relates the velocity of orbiting objects to the THE FATHER OF DARK MATTER-AND MORE 1 3 ry <p><a href="https://photos-of-space.tumblr.com/post/162261874067/fritz-zwicky-the-father-of-dark-matter" class="tumblr_blog">photos-of-space</a>:</p> <blockquote><p>Fritz Zwicky-The father of Dark Matter</p></blockquote>

Well this is awesome. (Swipe the photo for more). Repost @nasa ・・・ New planets outside our solar system! We discovered the most Earth-sized planets found in the habitable zone of a single star, called TRAPPIST-1. This system of seven rocky worlds-all of them with the potential for water on their surface-is an exciting discovery in the search for life on other worlds. The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water - key to life as we know it - under the right atmospheric conditions, but the chances are highest with the three in the habitable zone. This illustrations show planets of the TRAPPIST-1 system, including a travel poster and the possible surface of TRAPPIST-1f, one of the newly discovered planets.

KIC 8462852, otherwise known as Tabby’s star, is a real weirdo, celestially speaking. Over the last century, the star dimmed by 14 percent for no apparent reason, which led people to believe that it was surrounded by some sort of megastructure...because aliens. Obviously that’s not the case, but in the last four years, researchers watched a severe drop off in its brightness. Josh Simon and Ben Montet, researchers from Caltech, have been scratching their heads at data from NASA’s Kepler space telescope. “This star was already completely unique because of its sporadic dimming episodes. But now we see that it has other features that are just as strange, both slowly dimming for almost three years and then suddenly getting fainter much more rapidly,” said Simon. Montet continued, “It’s a big challenge to come up with a good explanation for a star doing three different things that have never been seen before. But these observations will provide an important clue to solving the mystery of KIC 8462852.” We can’t wait to see what this star’s deal is!
