HS-ESS1-2
Construct an explanation of the Big Bang theory based on astronomical evidence of light spectra, motion of distant galaxies, and composition of matter in the universe.
- Planets
In a first, astronomers spot the aftermath of an exoplanet smashup
Infrared light from a distant star appears to be leftovers of an impact between a pair of Neptune-sized worlds.
- Space
Weird black holes may reveal secrets of the early universe
Emerging evidence points to the existence of rogue black holes and other cosmic oddities — such as big black holes in tiny galaxies.
- Space
Experiment: A puzzling parallax helps stargazers
In this project, we explore how perspective, or parallax, can be used to measure the distances to objects such as stars.
- Space
Ghost particles paint a new picture of the Milky Way
Scientists tracked neutrinos from space to create a new map of our galaxy. It’s the first image of the Milky Way to be made without light.
- Space
Newfound gravitational waves may be from the biggest black holes in the universe
Observations of dead stars hint that ripples in spacetime — ripples light-years long — roll through our universe.
- Space
Scientists Say: Pulsar
These rapidly spinning dead stars send beams of radio waves into space like cosmic lighthouses.
- Space
Lightning dances through Jupiter’s skies much like it does on Earth
Data from NASA’s Juno spacecraft hint that Jupiter’s lightning extends in jagged steps as it does on Earth.
- Planets
In a first, telescopes have caught a star eating a planet
A burst of light and a cloud of dust are signs that a distant star swallowed a giant planet.
- Space
James Webb telescope catches newborn stars sculpting spiral galaxies
Dark voids riddle the galaxies, revealing new details about how stars alter their environments.
- Tech
A new solar-powered gel purifies water in a flash
The unusual, fruit-inspired structure of this material provides quick filtration that could satisfy people's daily water needs.
- Space
Scientists Say: Accretion Disk
Cosmic swirls of gas, dust and plasma, accretion disks reveal the shadowy silhouettes of black holes and more.
- Planets
Planets like Star Wars’ Tatooine could be fit for life
Like Luke Skywalker’s home, planets orbiting two stars may be plentiful. A new computer model suggests that many of those worlds could sustain life.
