We summarize the week's scientific breakthroughs every Thursday.
- Planetary Science
An ancient magma ocean may have once driven Earth’s magnetic field
Computer simulations of molten silicate under extreme temperatures and pressures may have just filled in a gap in the history of Earth’s magnetism.
- Space
50 years ago, scientists were studying why the sun’s corona is so hot
In 1970, scientists were hoping to learn why the sun’s corona is so hot during an eclipse. Fifty years later, the corona’s magnetic field may hold some answers.

China’s moon rover revealed what lies beneath the lunar farside
China’s Yutu-2 rover found layers of fine sand and coarse gravel under the surface of the moon’s farside.

NASA icon Katherine Johnson has died at the age of 101
The “Hidden Figure” captured the public’s admiration after the story of her career was publicized in a 2016 book and film.
- Space
What NASA’s InSight lander has learned about Mars’ magnetism and quakes
In its first 10 months, the InSight lander detected Marsquakes and an unexpectedly strong magnetic field at its landing site on the Red Planet.
- Physics
This fundamental constant of nature remains the same even near a black hole
A number that sets the strength of electromagnetic interactions isn’t altered by the extreme gravity around the Milky Way’s supermassive black hole.
- Astronomy
Molecular oxygen has been spotted beyond the Milky Way for the first time
Astronomers have detected molecular oxygen in another galaxy for the first time. The discovery is only the third sighting beyond our solar system.
- Space
An ancient galaxy grew massive — then oddly stopped making stars
After ferociously producing stars for a few hundred million years, this galaxy in the early universe gave up, and astronomers aren’t sure why.
- Space
ESA’s Solar Orbiter will be the first spacecraft to study the sun’s polar zones
ESA's Solar Orbiter is now on its way to the sun, beginning a nearly two-year journey.
- Earth
Here are 5 of the weirdest auroras, including the newly spotted ‘dunes’
A newfound type of aurora dubbed the “dunes” joins the ranks of black auroras, STEVE and other obscure auroral phenomena.
- Space
This is the first fast radio burst known to have a steady beat
Brief blasts of radio energy from other galaxies keep stumping astronomers, but one seems to be on a 16-day cycle, a new clue in an ongoing puzzle.
- Space
The wobbling orbit of a pulsar proves Einstein right, yet again
Astronomers have found a pulsar’s orbit being rocked to and fro as a neighboring white dwarf whips up spacetime, in accordance with general relativity.
