Neutrinos could reveal how fast radio bursts are launched
Highly magnetized stellar corpses called magnetars may be the source of two different cosmic enigmas: fast radio bursts and high-energy neutrinos.
- Space
Phosphine gas found in Venus’ atmosphere may be ‘a possible sign of life’
Astronomers have detected a stinky, toxic gas in Venus’ clouds that could be a sign of life, or some strange unknown chemistry.
- Space
A weirdly warped planet-forming disk circles a distant trio of stars
The bizarre geometry of a disk of gas and dust around three stars in the constellation Orion could be formed by “disk tearing” or a newborn planet.
- Astronomy
Check out the first-ever map of the solar corona’s magnetic field
Solar physicists watched waves in the sun’s corona to map the whole corona’s magnetic field. Future observers could use the same technique to predict solar eruptions.
- Astronomy
In a first, astronomers spotted a space rock turning into a comet
Scientists have caught a space rock in the act of shifting from a Kuiper Belt object to a comet. That process won’t be complete until 2063.
- Planetary Science
Jupiter’s moons could keep each other warm by raising tidal waves
Along with gravity from the enormous planet, tidal forces between Jupiter’s moons could generate a surprising amount of heat.
- Space
‘Exotic’ lightning crackles across Jupiter’s cloud tops
Newly spotted lightning, which could form thanks to ammonia antifreeze, is weaker but more frequent than any flashes seen on Jupiter before.
- Planetary Science
The Perseverance rover caps off a month of Mars launches
With the launch of NASA’s Perseverance rover, the rush to the Red Planet is under way.
- Space
To rehearse Perseverance’s mission, scientists pretended to be a Mars rover
Seven Mars scientists pretended to be the Mars Perseverance rover on a training exercise in the Nevada desert.
- Planetary Science
NASA’s Perseverance rover will seek signs of past life on Mars
NASA’s Perseverance rover will collect rocks and search for past life on Mars using lasers and zoomable cameras among other instruments.
- Astronomy
This is the first picture of a sunlike star with multiple exoplanets
A first family portrait reveals a weird cousin of the solar system: a star about the mass of the sun orbited — distantly — by two massive gas giants.
- Astronomy
Pinning down the sun’s birthplace just got more complicated
Many astronomers think that the sun was born in a loose association of thousands of stars. A new study suggests there’s another possibility.
