Putrid plants can reek of hot rotting flesh with one evolutionary trick
Some stinky plants independently evolved an enzyme to take the same molecule behind our bad breath and turn it into the smell of rotting flesh.
- Physics
A weird ice that may form on alien planets has finally been observed
High-pressure experiments generated the first direct observation of plastic ice, which has qualities of both crystalline ice and liquid water.

NASA’s James Webb Space Telescope could help solve these 5 exoplanet puzzles
A lot of people are focused on signs of alien life, but the space telescope will have a lot to say about exoplanet geology and formation.
- Astronomy
A nebula’s X-ray glow may come from a destroyed giant planet
Decades of constant X-ray emission from the Helix Nebula’s white dwarf suggest debris from a Jupiter-sized planet steadily rains upon the star.
- Space
‘Star Wars’ holds clues to making speedier spacecraft in the real world
Controlled fusion, solar sails or ion engines could someday help spaceships travel between star systems.
- Astronomy
The universe’s first supernovas probably produced water
Water may have formed less than 200 million years after the Big Bang, suggesting some conditions for life existed far earlier than previously thought.
- 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.
- Cosmology
A map of 14 million galaxies and quasars deepens a dark energy mystery
The DESI experiment shocked cosmologists with a hint that dark energy varies over time. Now, with more data, the conclusions hold up.
- Astronomy
Barnard’s star has at least one planet orbiting it after all
After decades of searching, a telltale gravitational wobble points to an exoplanet orbiting the nearby red dwarf every 3.15 days.
- Planetary Science
In a first, astronomers spot the afterglow of an exoplanet collision
A surge of infrared light from a remote star might have been a glow cast by the vaporized leftovers of an impact between Neptune-sized worlds.

50 years ago, astronomers challenged claims that Barnard’s star has a planet
Astronomers have been searching for planets around the sun’s close neighbor for decades.
- Astronomy
The North Star is much heavier than previously thought
Polaris is about five times as massive as the sun, new observations reveal. That’s around 50 percent heavier than what an earlier study found.
