Astronomers finally measure polarized light from exoplanet

An international team led by Dutch astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarized light from an exoplanet. They can deduct from the light ...

New CubeSat will observe the remnants of massive supernovas

Scientists at CU Boulder are developing a satellite about the size of a toaster oven to explore one of the cosmos' most fundamental mysteries: How did radiation from stars punch its way out of the first galaxies to fundamentally ...

Astronomers determine distances to 18 dwarf galaxies

Astronomers from the Special Astrophysical Observatory (SAO) in Nizhnij Arkhyz, Russia, have conducted photometric observations of dwarf galaxies identified by the ALFALFA survey. The results allowed the researchers to determine ...

A new look at sunspots

NASA's extensive fleet of spacecraft allows scientists to study the Sun extremely close-up—one of the agency's spacecraft is even on its way to fly through the Sun's outer atmosphere. But sometimes taking a step back can ...

The evolving chemistry of protoplanetary disks

Planets form from the gas and dust in disks that surround young stars. Chemicals in the disk that evaporate easily, called volatiles, include important molecules like water, carbon monoxide, nitrogen, as well as other simple ...

Gas reaches young stars along magnetic field lines

Astronomers have used the GRAVITY instrument to study the immediate vicinity of a young star in more detail than ever before. Their observations confirm a thirty-year-old theory about the growth of young stars: the magnetic ...
