The James Webb Space Telescope's MIRI instrument needs to cool down almost to absolute zero, the temperature where the motion of atoms stops, before it can start observing the universe.

Perihelion is the point at which an orbiting body is closest to the sun. The word comes from Greek and literally means around (peri) the sun (helios).

The sun's atmosphere has three layers: The photosphere, the chromosphere and the corona.

The upcoming Ax-1 mission is perhaps the beginning of a new era in human spaceflight — not because of the identity of the private astronauts, but because of the ecosystem that's emerging around them.

Earth is made up of several layers: the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core.

Artifacts from the first heavier-than-air powered flying machine, the first spacecraft to carry humans to land on the moon and the first Israeli to fly in space are headed into orbit with Ax-1.

The upcoming Ax-1 mission is perhaps the beginning of a new era in human spaceflight — not because of the identity of the private astronauts, but because of the ecosystem that's emerging around them.

Book your travel, buy your glasses, and get ready for the show of the decade on April 8, 2024

NASA's Ingenuity helicopter completed its 24th Martian flight on Sunday (April 3), a short repositioning hop that covered 154 feet (47 meters) in 69.5 seconds.

Since astronomers began finding exoplanets in the 1990s, they've uncovered a lot of hot Jupiters, and now NASA's most venerable telescope is playing meteorologist.

SpaceX will launch a former NASA astronaut and three paying customers on a journey to the International Space Station. That mission, called Ax-1, lifts off today (April 8)!

The first all-private crewed mission to the International Space Station is ready to fly, mission leaders announced today (April 7).

First came the "Maggots." Then the "Bugs." Now the latest infestation to take over NASA's Astronaut Office has been identified. The 23rd group of astronaut candidates has their nickname, "The Flies."

In just one night of observing, scientists detected a new record-breaker, the most distant megamaser known to date.

"Return To Space" is a new Netflix documentary chronicling SpaceX's role in returning America to crewed spaceflight

Former NASA astronaut Michael López-Alegría is about to fly to orbit with three paying passengers — but the trio aren't "space tourists," the veteran spaceflyer stresses.

The public-private partnership is providing internet connectivity to Ukraine, whose cities have been besieged by Russian forces since February.

The Lyrids are a prominent meteor shower that peaks in April. The famous shower caused by Comet Thatcher has been observed for more than 2,700 years.

The Lyrid meteor shower 2022 will peak on the night of April 22, a typical shower displays between five and 20 meteors an hour at the peak.

The surface of asteroid Bennu acts like an impact-absorbing crumple zone that protects the space rock from forming craters, a new study based on OSIRIS-REx observations reveals.

It may be possible to build a real, traversable wormhole, but only if our universe has extra dimensions, a team of physicists has found.
