Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found strong evidence of a giant planet orbiting a star in the stellar system closest to our own Sun. At just 4 light-years away from Earth, the Alpha Centauri triple star system has long been a compelling target in the search for worlds beyond our solar system.

Startup Orbital Operations has raised a seed round of funding to work on a high-performance orbital transfer vehicle that uses liquid hydrogen fuel and can stay in orbit for years.

A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet 3I/ATLAS, using the crisp vision of the NASA/ESA Hubble Space Telescope.

ESA's Planetary Defence Office responded promptly to the discovery of the comet, and has been tracking it since the beginning of July.

Now, Hubble's observations from space are allowing astronomers to more accurately estimate the size of the comet’s solid icy nucleus. The upper limit on the diameter of the nucleus is 5.6 km, but it could be as small as 320 m across, researchers report.

Though the Hubble images put tighter constraints on the nucleus size

Two small broadband satellites for Anuvu are ready for service after reaching geostationary orbit, their manufacturer Astranis said Aug.

It’s time for transformational leadership to reclaim America’s space agency’s mission-first legacy and restore the bold, achievement-oriented culture that once inspired the world.
