With Hubble, astronomers measured the mass of a single, isolated white dwarf – which is the surviving core of a burned-out star.
The white dwarf, called LAWD 37, is 56% the mass of our Sun: go.nasa.gov/3l31XyZ

For the First Time Hubble Directly Measures Mass of a Lone White Dwarf
Astronomers using NASA's Hubble Space Telescope have for the first time directly measured the mass of a single, isolated white dwarf.Andrea Gianopoulos (NASA)
Astronomers were able to determine this using “gravitational microlensing” – when the gravity of a foreground object warps the light coming from an object behind it.
The light from a background star was slightly deflected by the gravitational warping of space by LAWD 37.

NASA Announces Finalists in Challenge to Design Future Astronaut Food

Don't get me wrong, I'm glad research is being done, but food insecurity is caused purely by capitalist greed.
We already have way, way more food on Earth than we need to feed every human being, but corporations owning that food will rather it go to waste than feed someone for free.
