MAGIC - The MAGIC Telescope Web Server on La Palma Mysterious New 'Dark Flow' Discovered in Space As if the mysteries of dark matter and dark energy weren't vexing enough, another baffling cosmic puzzle has been discovered. Patches of matter in the universe seem to be moving at very high speeds and in a uniform direction that can't be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon "dark flow." The stuff that's pulling this matter must be outside the observable universe, researchers conclude. When scientists talk about the observable universe, they don't just mean as far out as the eye, or even the most powerful telescope, can see. Mysterious motions Scientists discovered the flow by studying some of the largest structures in the cosmos: giant clusters of galaxies. The X-rays scatter photons in the CMB, shifting its temperature in an effect known as the kinematic Sunyaev-Zel'dovich (SZ) effect.

Planck's law Planck's law (colored curves) accurately described black body radiation and resolved the ultraviolet catastrophe (black curve). Planck's law describes the electromagnetic radiation emitted by a black body in thermal equilibrium at a definite temperature. The law is named after Max Planck, who originally proposed it in 1900. It is a pioneer result of modern physics and quantum theory. For frequency ν, or for wavelength λ, Planckian radiation can be described thus: or where B denotes its spectral radiance, T its absolute temperature, kB the Boltzmann constant, h the Planck constant, and c the speed of light in the medium, whether material or vacuum.[1][2][3] The SI units are W·sr−1·m−2·Hz−1 for Bν(T) and W·sr−1·m−3 for Bλ(T). Introduction[edit] Every physical body spontaneously and continuously emits electromagnetic radiation. In the interior of a physical medium, radiation can be absorbed and emitted by matter.

James Webb Space Telescope (JWST) NASA Science Journal Cosmic Background Explorer The Cosmic Background Explorer (COBE), also referred to as Explorer 66, was a satellite dedicated to cosmology. Its goals were to investigate the cosmic microwave background radiation (CMB) of the universe and provide measurements that would help shape our understanding of the cosmos. This work provided evidence that supported the Big Bang theory of the universe: that the CMB was a near-perfect black-body spectrum and that it had very faint anisotropies. History[edit] In 1974, NASA issued an Announcement of Opportunity for astronomical missions that would use a small- or medium-sized Explorer spacecraft. Launch of the COBE spacecraft November 18, 1989. NASA accepted the proposal provided that the costs be kept under $30 million, excluding launcher and data analysis. COBE was originally planned to be launched on a Space Shuttle mission STS-82-B in 1988 from Vandenberg Air Force Base, but the Challenger explosion delayed this plan when the Shuttles were grounded.

Video inpainting software deletes people from HD video footage In a development sure to send conspiracy theorists into a tizzy, researchers at the Max Planck Institute for Informatics (MPII) have developed video inpainting software that can effectively delete people or objects from high-definition footage. The software analyzes each video frame and calculates what pixels should replace a moving area that has been marked for removal. In a world first, the software can compensate for multiple people overlapped by the unwanted element, even if they are walking towards (or away from) the camera. See the incredible video demonstration after the break. View all The software was developed by a team led by Prof. The software was inspired by shift maps – which take a portion of footage from one moment in time and move it to another moment in time to fill in the occluded area.

The Liverpool Telescope First Image of Another Multi-Planet Solar System | Universe Today Want to stay on top of all the space news? Follow @universetoday on Twitter Here’s what we’ve all been waiting for: for the first time, astronomers have taken pictures of a multi-planet solar system, much like ours, orbiting another star. This coincides with announcement of the first visible light image of an extrasolar planet taken by the Hubble Space Telescope. This new solar system orbits a dusty young star named HR8799, which is 140 light years away and about 1.5 times the size of our sun. “We’ve been trying to image planets for eight years with no luck and now we have pictures of three planets at once,” said Bruce Macintosh, an astrophysicist from Lawrence Livermore National Laboratory. Astronomers have known for a decade through indirect techniques that the sun was not the only star with orbiting planets. “But we finally have an actual image of an entire system,” Macintosh said. The planets are 24, 37 and 67 times the Earth-sun separation from the host star.
