What time is it? The answer, no matter what your initial reference may be, will always trace back to the atomic clock. The international standard for time is set by atomic clocks — room-sized apparatuses that keep time by measuring natural vibration of atoms in a vacuum. Researchers have come up with a new approach to atomic timekeeping that may enable more stable and accurate portable atomic clocks, potentially the size of a Rubik’s cube.

A team of researchers is embarking on a collaborative project to ensure that the autonomous robots we build in the future will be safer, making decisions that are ethical and follow legislation on robotics.
Titan, Saturn’s largest moon, is a peculiar place. Unlike any other moon, it has a dense atmosphere. It has rivers and lakes made up of components of natural gas, such as ethane and methane. It also has windswept dunes that are hundreds of yards high, more than a mile wide and hundreds of miles long — despite data suggesting the body to have only light breezes.
NASA's new Orion spacecraft made a "bull's-eye" Pacific splashdown following a dramatic journey 3,604 miles beyond Earth. The achievement opens a new era of human exploration to put people on Mars.
A study of "MY Camelopardalis" binary system shows that the most massive stars are made up by merging with other smaller stars, as predicted by theoretical models.
The results of four years of observations from the ESA's Planck satellite reveals relic radiation (the most ancient light in the Universe). This light has been measured precisely across the entire sky for the first time, in both intensity and polarization, thereby producing the oldest image of the Universe. This primordial light lets us "see" some of the most elusive particles in the Universe: dark matter and relic neutrinos.
New observations with ESO’s Very Large Telescope in Chile have revealed alignments over the largest structures ever discovered in the Universe. A European research team has found that the rotation axes of the central supermassive black holes in a sample of quasars are parallel to each other over distances of billions of light-years.
The Soyuz TMA-13M crew, European Space Agency (ESA) astronaut Alexander Gerst, Roscosmos cosmonaut Max Suraev, and NASA astronaut Reid Wiseman, in their Soyuz spacecraft that will fly them back to Earth after almost six months on the International Space Station.
Nexio simulation is a French SME located in Toulouse and specialized in electromagnetic simulation software for marine, space, defense and aeronautics domains applications.
New data obtained by NASA’s GRAIL mission reveals that the Procellarum region on the near side of the moon — a giant basin often referred to as the “man in the moon” — likely arose not from a massive asteroid strike, but from a large plume of magma deep within the moon’s interior.
Scientists are to turn the Moon into a giant particle detector to help understand the origin of Ultra-High-Energy (UHE) cosmic rays — the most energetic particles in the Universe.
On a July night this summer, a 5,200-pound balloon gondola hangs from a crane and moves toward the open doors of a building at the Johns Hopkins University Applied Physics Lab in Laurel, Md. The telescopes and instruments carried by the gondola, which are part of NASA’s Balloon Observation Platform for Planetary Science (BOPPS), are calibrated by taking a long look at the stars and other objects in the sky.
Hunting from a distance of 27,000 light years, astronomers have discovered an unusual carbon-based molecule – one with a branched structure – contained within a giant gas cloud in interstellar space. Like finding a molecular needle in a cosmic haystack, astronomers have detected radio waves emitted by isopropyl cyanide. The discovery suggests that the complex molecules needed for life may have their origins in interstellar space.
The Soyuz TMA-14M rocket is launched with Expedition 41 Soyuz Commander Alexander Samokutyaev of the Russian Federal Space Agency (Roscosmos) Flight Engineer Elena Serova of Roscosmos, and Flight Engineer Barry Wilmore of NASA, Friday, September 26, 2014 at the Baikonur Cosmodrome in Kazakhstan.
NASA's effort to identify potentially dangerous space rocks has taken a hit. On September 15, 2014, the space agency's inspector general released a report blasting NASA's Near Earth Objects program, which is meant to hunt and catalog comets, asteroids and relatively large fragments of these objects that pass within 28 million miles of Earth. The purpose is to protect the planet against their potential dangers.
The sun emits a mid-level solar flare. NASA's Solar Dynamics Observatory captured images of the flare, which erupted on the left side of the sun. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however—when intense enough—they can disturb the atmosphere in the layer where GPS and communications signals travel.
Future asteroid mining operations and how we deal with an impending strike could be influenced by research on a potential NASA mission that's being done by team that includes a University of Alabama in Huntsville scientist.
The Apollo 11 Lunar Module Eagle, in a landing configuration was photographed in lunar orbit from the Command and Service Module Columbia. Inside the module were Commander Neil A. Armstrong and Lunar Module Pilot Buzz Aldrin. The long rod-like protrusions under the landing pods are lunar surface sensing probes. Upon contact with the lunar surface, the probes sent a signal to the crew to shut down the descent engine.
As left over building blocks of the solar system's formation, asteroids are of significant interest to scientists. Resources, especially water, embedded within asteroids could be of use to astronauts traveling through deep space. Likewise, asteroids could continue to be destinations for robotic and human missions as NASA pioneers deeper into the solar system, to Mars and beyond.
This new Hubble image shows NGC 1566, a beautiful galaxy located approximately 40 million light-years away in the constellation of Dorado (The Dolphinfish). NGC 1566 is an intermediate spiral galaxy, meaning that while it does not have a well-defined bar-shaped region of stars at its center — like barred spirals — it is not quite an unbarred spiral either.
A saucer-shaped test vehicle holding equipment for landing large payloads on Mars is shown in the Missile Assembly Building at the US Navy's Pacific Missile Range Facility in Kaua’i, Hawaii. The vehicle, part of the Low-Density Supersonic Decelerator project, will test an inflatable decelerator and a parachute at high altitudes and speeds over the Pacific Missile Range.
The sun shines through a truss-based radiator panel and a primary solar array panel on the Earth-orbiting International Space Station (ISS) in this photograph taken by an Expedition 38 crew member on January 2, 2014. The crew on the ISS awaits the first commercial resupply mission to the ISS by Orbital Sciences, Orbital-1.
Peering into the far reaches of the solar system, astronomers have spied a pink frozen world 7½ billion miles from the sun. It's the second such object to be discovered in a region of space beyond Pluto long considered a celestial wasteland.
An Orbital Sciences Corporation Antares rocket is seen on launch Pad-0A at NASA's Wallops Flight Facility. The Antares will launch a Cygnus spacecraft on a cargo resupply mission to the International Space Station.
At 06:45 UTC on March 23, NASA's Aqua satellite flew overhead and the Moderate Resolution Imaging Spectroradiometer or MODIS instrument captured a visible image of the storm. In the image, Gillian's eye had already started to fill in with clouds and was surrounded by a thick band of thunderstorms wrapping around the center of circulation.
The Soyuz TMA-11M rocket, adorned with the logo of the Sochi Olympic Organizing Committee and other related artwork, is seen in this long exposure photograph, as the service structure arms are raised into position at the launch pad on Tuesday, November 5, 2013, Baikonur Cosmodrome in Kazakhstan.
