Dark matter, the substance that is thought to make up more than a quarter of the universe, remains a greater mystery. Scientists have now stated that earlier findings, seemingly discovering dark matter particles, are not correct.
The European Space Agency (ESA) switched off its Planck space telescope for good at 12:10:27 UT, Thursday. Planck spent over four years peering back in time, studying background radiation from the Big Bang that gave birth to our Universe.
Scientists have announced that the $2 billion particle detector, the Alpha Magnetic Spectrometer (AMS), mounted on the International Space Station (ISS), may have detected the signature of dark matter annihilation.
Researchers have hinted "big news" for the world in the search for dark matter. The physicist in charge of the Alpha Magnetic Spectrometer (AMS) experiment dropped a hint at the annual meeting of the American Association for the Advancement of Science.
NASA and the European Space Agency this week announced that NASA would be participating in the ESA’s Euclid mission scheduled for launch in 2020. Euclid is a space telescope whose purpose is to investigate cosmic dark matter and dark energy.
University of Victoria physicists concluded earth may be traveling through dark matter walls, on its way through a universe of force fields dividing dark matter bubbles created after the big bang, and detecting this should be possible with today's tools.
New research in dwarf galaxies, satellites of our own, is now helping scientists better understand dark matter. Peering into the darkest depths of these neighboring systems have shown nothing, and that nothingness is what everyone is excited about.
Dark matter is defined by NASA as “Name given to the amount of mass whose existence is deduced from the analysis of galaxy rotation curves but which until now, has escaped all detections.” That’s about as accurate as its definitions get.
A halo detected around a distant cluster of galaxies is the strongest evidence yet for dark matter...The discovery is a milestone in a 70-year search for a substance that has never been seen yet accounts for nearly all of the mass in the universe.

The Cosmic microwave background (CMB) as observed by Planck, is a snapshot of the oldest light in our Universe, imprinted on the sky when the Universe was just 380 000 years old

The solar system takes 1 cosmic year lasting about 225-250 million years to orbit the Milky Way's galactic centre but during that time it oscillates above and below the galactic plane every 32 million years or so.

A slice of the Bolshoi supercomputer simulation of the universe, which is based on the Lambda Cold Dark Matter (ΛCDM) cosmogeny that hypothesizes a cosmic web of dark matter underlying the large-scale universe, driving galaxy and galaxy cluster formation through gravitational effects on ordinary matter.
