An illustration of the galaxy system CRISTAL-02, with an outflow of gas almost as large as the system itself, suggesting that star-forming gas is streaming away.

JWST spots an early-universe outflow that may shut galaxies down

JWST and ALMA observed CRISTAL-02 as it appeared 1 billion years after the Big Bang.
Researchers reported a gas plume nearly as large as the galaxy system itself escaping at high speed.
The finding supports the idea that merger-driven winds can quench star formation in early galaxies.

‘Highly Plausible’ Aliens on Europa Are Earthlings’ Descendants, Study Says

Could Europa Already Host Earth Life? A Study Revives a Panspermia Question

A new study examines whether Earth bacteria could reach Europa on dust grains.
The paper argues the transport pathway is highly plausible over long timescales.
If life is found on Europa, ancestry could become a central scientific question.
The study adds a natural-transfer dimension to planetary protection debates.

Canada’s proposed POET microsatellite would target Earth-sized worlds around ultracool stars

Canada’s proposed POET mission would focus on Earth-sized planets around small, cool stars.
A 20-centimeter telescope would observe in near-UV, visible and near-infrared bands.
The mission builds on prior Canadian microsatellite programs MOST and NEOSSat.

Hubble’s 25-Year View of the Crab Nebula Shows a Supernova Remnant Still in Motion

Live Science says Hubble images taken 25 years apart show major changes in the Crab Nebula.
The object is about 6,500 light-years away in Taurus.
The comparison offers new insight into the nebula’s evolution, structure and pulsar-driven growth.

NASA’s Nancy Grace Roman Space Telescope stands fully assembled, following the integration of its two major segments, in the clean room at the agency’s Goddard Space Flight Center in Greenbelt, Maryland. The mission is slated to launch by May 2027, but the team is on track for launch as early as fall 2026.

NASA’s Roman Space Telescope Reaches a Visible Milestone Ahead of Launch

NASA says Roman has completed construction and is wrapping up prelaunch testing.
The observatory is slated to launch by May 2027 and could fly as early as fall 2026.
NASA will display the fully integrated telescope at Goddard on April 21.
The agency says Roman will deliver deep, panoramic surveys of the cosmos.

NASA’s IXPE observed the outer rim of the supernova remnant highlighted in purple in the inset. Data from IXPE is combined with data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. The yellow represents low-energy X-rays, while blue shows high-energy X-rays detected by Chandra and XMM-Newton. The starfield in the image comes from the National Science Foundation’s National Optical-Infrared Astronomy Research Laboratory (NOILab).

NASA's IXPE Finds Expansion Mystery Solved in 2,000-Year-Old Supernova

NASA's IXPE detected a 'reflected shock effect' at the rim of RCW 86 where its unusually rapid expansion has halted
The Chandra observatory had previously found a low-density cavity surrounding the remnant that caused abnormally fast expansion
The new finding explains the expansion halt as a shock wave bouncing back from the cavity's edge, confirmed by IXPE's unique polarimetric capability

Science Through Shadows: How Eclipses, Occultations, and Transits Reveal the Universe

Eclipses, occultations, and transits encode scientific information about the size, shape, and atmospheric composition of celestial bodies
Stellar occultations revealed Pluto's atmosphere and the rings of Uranus and Neptune before spacecraft visits
The transit method drove the exoplanet revolution, with Kepler cataloguing thousands of confirmed worlds
Transmission spectroscopy with JWST enables direct detection of molecules including CO2 in exoplanet atmospheres
The technique stretches from Eratosthenes calculating Earth's circumference to modern searches for biosignatures on habitable-zone planets
