    Scientists have discovered that a mysterious pressure dubbed "dark energy" makes up about 68% of the total energy content of the cosmos, but so far we don't know much more about it. Exploring the nature of dark energy is one of the primary reasons NASA is building the Wide Field Infrared Survey Telescope (WFIRST), a space telescope whose measurements will help illuminate the dark energy puzzle. With a better understanding of dark energy, we will have a better sense of the past and future evolution of the universe. [...]

    The Large Magellanic Cloud, or LMC, is one of our nearest galactic neighbors, at only 163,000 light years from Earth. With its sibling the Small Magellanic Cloud, these are among the nearest dwarf satellite galaxies to the Milky Way. The LMC is also the home of various stellar conglomerates and is an ideal laboratory for astronomers to study the processes that shape galaxies. [...]

    This image, taken with the NASA/ESA Hubble Space Telescope, focuses on an object named UGC 695, which is located 30 million light-years away within the constellation Cetus (the Sea Monster), also known as the Whale. A bounty of diverse background galaxies is also visible in this image. [...]

    Saturn is so beautiful that astronomers cannot resist using the Hubble Space Telescope to take yearly snapshots of the ringed world when it is at its closest distance to Earth. [...]

    When two black holes collide, they merge into one bigger black hole and ring like a struck bell, sending out ripples in space and time called gravitational waves. Embedded in these gravitational waves are specific frequencies, or tones, which are akin to individual notes in a musical chord. [...]

    A few months from now will see the launch of the first European satellite to demonstrate how onboard artificial intelligence can improve the efficiency of sending Earth observation data back to Earth. Dubbed ɸ-Sat, or PhiSat, this revolutionary artificial intelligence technology will fly on one of the two CubeSats that make up the FSSCat mission—a Copernicus Masters winning idea. [...]

    RUDN University mathematician has proposed a method for calculating the optimal trajectory of spacecraft with electric propulsion, whose thrust is thousands times less than chemical one has, but it is able to work for years. These motors are best suited for interplanetary missions. Mathematicians calculated the flight parameters of the space probe with such motor to Mars and Mercury. The paper is published in the journal Cosmic Research. [...]

    With more than 4,000 exoplanets—planets orbiting stars other than our sun—discovered so far, it may seem like we are on the cusp of finding out whether we are alone in the universe. Sadly though, we don't know much about these planets—in most cases just their mass and their radius. [...]

    Six astronauts, five space agencies and a fresh start into underground worlds to help prepare for living on other planets. ESA's latest training adventure will equip an international crew with skills to explore uncharted terrains on the Moon and Mars, this time with a focus on the search for water. [...]

    Every spring, the sun shines on the side of the stack of layers at the North Pole of Mars known as the north polar layered deposits. The warmth destabilizes the ice and blocks break loose. [...]
