An active galaxy nucleus (AGN) contains a supermassive black hole that is vigorously accreting material. It typically ejects jets of particles that move at close to the speed of light, ra...

Near Earth Objects (NEOs) are small solar system bodies whose orbits sometimes bring them close to the Earth. NEOs are consequently potential collision threats, but scientists are also in...

The Kepler mission and its extension, called K2, discovered thousands of exoplanets. It detected them using the transit technique, measuring the dip in light intensity whenever an orbitin...

Dust is a critical component in the Martian atmosphere. It influences the atmosphere's circulation by heating or cooling it and is in turn redistributed around the planet by atmospheric w...

The formation and growth of galaxies in the early universe is a key research topic for future giant telescopes like the Giant Magellan Telescope and space missions like the James Webb Spa...

When a star like our Sun gets to be old, in another seven billion years or so, it will no longer be able to sustain burning its nuclear fuel. With only about half of its mass remaining it...

The Arches cluster is a massive star cluster located in the Galactic Center region of our galaxy, about one hundred light-years from the galaxy's supermassive blackhole, SgrA*, and about ...

A Public Collection for Science With a large number of scientific journals ranging from general science to small subfields, it’s impossible for researchers or libraries to subscribe...

Our Milky Way galaxy has probably collided or otherwise interacted with other galaxies during its lifetime; such interactions are common cosmic occurrences. Astronomers can deduce the his...
