A Western University team led by Jan Cami used JWST's MIRI instrument to image planetary nebula Tc 1, finding C60 buckyballs confined to a hollow shell around the white dwarf and revealing an unexplained question-mark structure at the center.

SpaceX targets April 27 to launch ViaSat-3 F3 to the Asia-Pacific, ending Falcon Heavy's longest gap and capping a constellation that lost 90% of its first satellite to an antenna failure.

GPS III SV10 'Hedy Lamarr' lifts off April 21, completing a 32-satellite navigation constellation with optical crosslink tech never before flown on a GPS satellite.

Ship 39 and Booster 19 have each completed full-duration Raptor 3 engine tests at Starbase, with Flight 12 now targeting May 2026.

Amazon will acquire Globalstar for about $11.57 billion and inherit the company's iPhone satellite partnership, accelerating its Starlink challenge and its rebranded Amazon Leo constellation.

A 170,000-year visitor from the Oort Cloud has brightened faster than expected, reaching magnitude 4.7 and growing a 10-degree ion tail as it heads for its closest solar approach on April 19.

Webb telescope finds a Jupiter-sized planet orbiting a tiny red dwarf has fewer heavy elements in its atmosphere than its own star, defying all existing formation theories.

The first dual-coronagraph record of a Kreutz sungrazer's destruction and a pre-print tracing the comet's 1,663-year orbit to a daylight comet of 363 AD are reshaping models of cometary survival and the family's ancient genealogy.

The Kreutz sungrazer broke apart approximately six hours before reaching its closest point to the Sun on April 4, peaking at magnitude -0.6 in coronagraph imagery before its nucleus shattered. Only submicron dust debris emerged on the far side, leaving nothing visible from the ground.

The farthest Kreutz sungrazer ever discovered will pass just 161,000 kilometers above the Sun's surface on Saturday, threading the inner solar corona in a make-or-break encounter that could produce a comet visible in broad daylight or end in total disintegration.

NASA's Hubble Space Telescope caught comet C/2025 K1 fragmenting into at least four pieces across three days, marking the closest-to-breakup observation in the telescope's history.

The Y Combinator graduate plans an 88,000-satellite constellation for orbital AI compute, backed by Benchmark and EQT Ventures.
