Astronomers Scan the Center of the Milky Way for Any Sign of Intelligent Civilizations. Nothing but Silence.
Are there civilizations somewhere else in the Universe? Somewhere else in the Milky Way? That’s one of our overarching questions, and an answer in the affirmative would be profound.
Hope for the future of space exploration lies at the heart of SpaceX's new 'Polaris' missions
SpaceX aims to make progress in space and on Earth with its new venture, the Polaris Program. And the team behind it couldn't be more excited.
Astronomers see Dead Planets Crashing Into Dead Stars
When our Sun dies, the Earth will die with it. As a star of middling mass, the Sun will end its life by swelling into a red giant star. After a last cosmic moment of brilliance, the remnant core of the Sun will collapse into a white dwarf. This won’t occur for billions of years, but the mass and composition of the Sun means a white dwarf is its inevitable fate.
FAA pushes back review of SpaceX's Starship to March 28
The first orbital launch of SpaceX's Starship Mars rocket has been pushed back by at least another month.
Meet the four private Polaris Dawn astronauts SpaceX will launch into orbit this year

NASA has put together some freely available e-cards that feature iconic space photos with special Valentine's Day messages attached.
Cosmic robbery: New study explains how smaller galaxies lose their dark matter
Large galaxies may steal dark matter from smaller galaxies they nearly collide with, new research suggests.
Water was Already Here Before the Earth Formed
Where did Earth’s water come from? That’s one of the most compelling questions in the ongoing effort to understand life’s emergence. Earth’s inner solar system location was too hot for water to condense onto the primordial Earth. The prevailing view is that asteroids and comets brought water to Earth from regions of the Solar System beyond the frost line.
How Galaxies Can (Rarely) Lose Their Dark Matter
A careful study of cosmological simulations shows that dark matter–less galaxies aren't impossible — just really rare.
Billionaire's 'Polaris Program' to set space records on SpaceX Dragon, Starship
The billionaire commander of the first "all-civilian" space mission has now filed a new flight plan, underwriting a series of three SpaceX launches to rapidly advance human spaceflight capabilities.
Moon group pushes for protection of ultraquiet lunar far side

Jared Isaacman, the billionaire businessman who bankrolled the first human space mission with all private citizens last year, announced plans Monday for up to three more SpaceX flights, a privately-funded program that will include the first commercial spacewalk, and ultimately a ride on the giant Starship rocket ship.
Inventing the future of Navigation
Video: 00:05:15
Many of the experts that designed and oversaw the Galileo satnav system are now supporting cutting-edge European companies in the development of new navigation technologies and services. The result is ESA’s Navigation Innovation and Support Programme, NAVISP.
NAVISP is looking into all kinds of clever ideas about the future of navigation: ways to improve satellite navigation, alternative positioning systems and, new navigation services and applications. Working in partnership with European industry and researchers, more than 200 NAVISP projects have been initiated so far.
NAVISP is divided into three elements, the first looking into improving and expanding satellite navigation, as well as establishing novel ‘positioning, navigation and timing’ (PNT) services. NAVISP’s second element focuses on innovation for competitiveness, developing all kinds of new PNT products and services. Its third element covers support to Member State priorities, including support for national testbeds and programmes.
Astronomy Jargon 101: Hubble’s Law
In this series we are exploring the weird and wonderful world of astronomy jargon! You’ll expand your horizons with today’s topic: Hubble’s Law!
In 1929 astronomer Edwin Hubble made a remarkable measurement. Earlier in that decade, he had discovered that the Andromeda Nebula was not a nebula at all, but an entirely different galaxy completely separated from the Milky Way by millions of light-years of cold, hard nothing. He then expanded that initial discovery and began compiling a catalog of galaxies and their distances from us.
