Opportunity did not answer NASA’s final call, and it’s now gone to us. It roved a staggering 45.16 kilometers across the red planet.
The scientists waited to hear some response from their long-silent rover, which had been engulfed in a global dust storm last June, likely coating its solar panels in a fatal layer of dust. Since then, the team of scientists and engineers have sent more than 835 commands, hoping the rover will wake up from its long slumber—that perhaps winds on Mars might have blown off some of the dust that covered the panels.
So on Tuesday night, they listened. They reminisced. But in the end, no response came.
The brightest quasar in the early universe. It shines with a brightness equivalent to 600 trillion suns, is at a distance of 12.8 billion light years away and produces 10,000 stars per year. “We don’t expect to find many quasars brighter than that in the whole observable universe.”
Researchers have devised a new model for the Universe – one that may solve the enigma of dark energy. Their new article, published in Physical Review Letters, proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension.

This oblique perspective view was generated using a digital terrain model and Mars Express data gathered over orbits 18042 (captured on 4 April 2018), 5726, 5692, 5654, and 1412. The crater itself is centred at 165° E, 73° N on the martian surface. The image has aresolution of roughly 21 metres per pixel.
This image was created using data from the nadir and colour channels of the High Resolution Stereo Camera (HRSC). The nadir channel is aligned perpendicular to the…Read more
What is the Hubble Ultra-Deep Field? We\’ll journey with the Hubble telescope as we peer deep into space and discover it. This is Eric Whitacre\’s \”Deep Field: The Impossible Magnitude of our Universe\” a unique film and musical experience inspired by one of the most important scientific discoveries of all time: the Hubble Telescope\’s Deep Field image.
Virgin Galactic “SpaceShipTwo” reaches space during test flight
A Virgin Galactic rocket plane blasted to the edge of space on December 13 and returned safely to the California desert, capping off years of difficult testing to become the first U.S. commercial human flight to reach space since America’s shuttle program ended in 2011.
The test flight foreshadows a new era of civilian space travel that could kick off as soon as 2019, with British billionaire Richard Branson’s Virgin Galactic battling other billionaire-backed ventures, like Amazon.com founder Jeff Bezos’ Blue Origin, to be the first to offer suborbital flights to fare-paying tourists.

Scientists may have solved one of the biggest questions in modern physics, with a new paper unifying dark matter and dark energy into a single phenomenon: a fluid which possesses ‘negative mass”. This astonishing new theory may also prove right a prediction that Einstein made 100 years ago.
Assuming they’re right: the stuff that holds galaxies together has turned out to be the same stuff that makes the universe expand. A fluid made of negative m…Read more
Join NASA as InSight is set to land on the surface of Mars at Elysium Planitia on 26 November 2018. Here it\’ll deploy a seismometer and burrow a heat probe to investigate the interior of Mars.
The landing a success, here is the first image: https://pbs.twimg.com/media/Ds9EYfxXoAAPNmx.jpg
