Dead star's double debris ring offers a preview of the Solar System's end

New Capabilities

Operates the Very Large Telescope, which collected the J1328−1450 spectra

The white dwarf J1328−1450 sits about 1,600 light years away, the burnt-out core of a star like the Sun. Two rings of glowing gas circle it, separated by an empty gap.

Diskless white dwarf powers 1,000-year shock wave that shouldn't exist

New Capabilities

As of September 2026: Operated the telescope that imaged the shock

A dead star 730 light-years away is producing a shock wave it has no business making. The white dwarf RXJ0528+2838 has been ejecting material for at least 1,000 years, yet it lacks the accretion disk that normally drives such outflows.

Astronomers confirm youngest known planet, a baby Jupiter still forming

New Capabilities

As of September 2026: Operated the Very Large Telescope that detected the candidate planet

Astronomers have confirmed a planet less than a million years old, the youngest ever found. Elias 2-24 b is a Jupiter-size world still gathering gas from the disk of dust around its host star, 450 light-years from Earth.

Wandering black hole caught feeding from its gravitational wake

New Capabilities

As of September 2026: Provided the key observational data

Astronomers have caught a wandering black hole feeding from its own wake. The 35,000-solar-mass object sits outside the star-forming disk of the dwarf galaxy UGCA 320, about 20 million light-years from Earth, pulling gas from the dense trail its gravity leaves behind.

Astronomers capture first direct image of a cosmic web filament

New Capabilities

As of May 2026: Operates the telescope and instrument used

On May 16, 2026, Davide Tornotti and an international team published the sharpest direct image of a cosmic web filament. The strand stretches 3 million light-years, linking two galaxies with active supermassive black holes as they appeared 12 billion years ago.
