MS-ESS1-3
Analyze and interpret data to determine scale properties of objects in the solar system.
- Space
Moon-sized white dwarf is the smallest ever found
This dead star is also spinning very fast and has an amazingly powerful magnetic field.
- Space
Spin in this Milky Way bar may show cosmic dark matter does exist
A method akin to studying a tree’s rings reveals the timeline of a slowdown in those stars at the heart of our Milky Way galaxy.
- Space
Huge arc of galaxies is surprising and puzzling cosmologists
The arc appears to violate a cosmic rule that on such large scales, matter will be evenly distributed.
- Space
The Milky Way’s ‘yellowballs’ are clusters of baby stars
The mysterious cosmic objects — first spotted by citizen scientists — turn out to be infant stars of various masses.
- Space
Stars made of antimatter could lurk in our galaxy
Fourteen sources of gamma rays in our galaxy look like they could be antistars — celestial bodies made of antimatter.
- Planets
The pebbled path to planets
Small pebbles zipping through a sea of gas may give rise to mighty planets.
- Space
Here’s why people picked certain stars as constellations
Patterns of human eye movement help explain why particular sets of stars form iconic shapes, a high school student showed.
- Planets
Signs of a hidden Planet Nine in our solar system may be an illusion
Hints of the remote planet, also called Planet X, relied on clumped up orbits of bodies beyond Neptune. A new study suggests that clumping doesn’t exist.
- Space
Let’s learn about the moon
The moon is Earth’s nearest neighbor, and its gravity helps stabilize the planet’s climate and creates the tides.
- Space
Scientists Say: Planet
Planets have to orbit a star, be big enough to form a sphere and keep other objects out of their path around their star.
- Chemistry
Extreme pressure? Diamonds can take it
Diamond retains its structure even at extreme pressures, which could reveal how carbon behaves in the cores of some exoplanets.
- Space
Exploding neutron star proves to be energy standout of the cosmos
This is what scientists had suspected. But until one showed up outside our galaxy, they couldn’t be sure. Now they are.
