We summarize the week's scientific breakthroughs every Thursday.
- Astronomy
Mysterious ‘little red dot’ galaxies have a possible origin story
Compact ruddy galaxies seen by the James Webb telescope confound astronomers. Having very little spin at birth may explain the galaxies’ small sizes.
- Planetary Science
In a first, the Webb telescope found a planet by actually ‘seeing’ it
Finding a Saturn-sized world around the young star TWA 7 could pave the way for the Webb space telescope’s direct observation of other exoplanets.
- Astronomy
Two spacecraft created their first images of an artificial solar eclipse
The Proba-3 spacecraft succeed at creating solar eclipses, kicking off a two-year mission to study the sun’s mysterious outer atmosphere, the corona.
- Space
Distant nebulae star in one of the first images from the Rubin Observatory
These are the first public images collected by the Chile-based observatory, which will begin a decade-long survey of the southern sky later this year.
- Astronomy
Black hole–shredded megastars power a new class of cosmic explosions
These explosions, called extreme nuclear transients, shine for longer than typical supernovas and get 30 to 1,000 times as bright.
- Space
Here’s how a collision of star remnants launches a gleaming jet
A computer simulation shows how two neutron stars of unequal mass merge, form a black hole and spit out a jet of high energy matter.
- Planetary Science
A possible new dwarf planet skirts the solar system’s edge
For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.
- Space
A private Japanese spacecraft failed on its way to the moon’s surface
The spacecraft’s owner, ispace, is attempting to land these crafts to commercialize lunar resources.
- Astronomy
A dwarf galaxy just might upend the Milky Way’s predicted demise
The Milky Way may merge with the Large Magellanic Cloud in 2 billion years, not Andromeda, contrary to previous findings.
- Planetary Science
Venus’ tectonics may be actively reshaping its surface
Circular landforms speckling the Venusian surface may be the work of tectonic activity.
- Space
A passing star could fling Earth out of orbit
Simulations show that the star's tug could send Mercury, Venus or Mars crashing into Earth — or let Jupiter eject our world from the solar system.
- Space
Perseverance takes the first picture of a visible Martian aurora
A faint yet visible Martian aurora is the first instance of the phenomenon spotted from another planet's surface.
