NASA planet hunter on its way to orbit

Science Daily Astronomy - Thu, 2018-04-19 10:57
NASA's Transiting Exoplanet Survey Satellite (TESS) launched on the first-of-its-kind mission to find worlds beyond our solar system, including some that could support life. Researchers will use spectroscopy to determine a planet's mass, density and atmospheric composition. Water, and other key molecules, in its atmosphere can give us hints about a planets' capacity to harbor life.

Optimizing space travel efficiency

Science Daily Astronomy - Wed, 2018-04-18 19:43
Sending a human into space and doing it efficiently presents a galaxy of challenges. Scientists have explored ways to integrate the logistics of space travel by looking at a campaign of lunar missions, spacecraft design, and conducting research, to create a framework to optimize fuel and other resources.

Meteorite diamonds tell of a lost planet

Science Daily Astronomy - Wed, 2018-04-18 14:48
Scientists have examined a slice from a meteorite that contains large diamonds formed at high pressure. The study shows that the parent body from which the meteorite came was a planetary embryo of a size between Mercury to Mars.

Black hole and stellar winds form giant butterfly, shut down star formation in galaxy

Science Daily Astronomy - Wed, 2018-04-18 14:15
Researchers have completed an unprecedented 'dissection' of twin galaxies in the final stages of merging. The new study explores a galaxy called NGC 6240. While most galaxies in the universe hold only one supermassive black hole at their center, NGC 6240 contains two -- and they're circling each other in the last steps before crashing together.

Martian moons model indicates formation following large impact

Science Daily Astronomy - Wed, 2018-04-18 14:15
Scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant impact thought to have resulted in the Earth-moon system. Their work shows that an impact between proto-Mars and a dwarf-planet-sized object likely produced the two moons.

340,000 stars' DNA interrogated in search for sun's lost siblings

Science Daily Astronomy - Wed, 2018-04-18 09:20
Astronomers have revealed the 'DNA' of more than 340,000 stars in the Milky Way, which should help them find the siblings of the sun, now scattered across the sky. This is the first major announcement of an ambitious survey as part of a quest to uncover the formulation and evolution of galaxies -- after the Australian-led Galactic Archaeology survey, called GALAH, commenced three years ago.
