The Moon reaches apogee, the farthest point from Earth in its orbit, at 5:46 A.M. EDT. At that time, our satellite will stand 251,996 miles (405,548 km) away. With the Moon sinking low in the hours ...

Temperature is a measure of the average energy of a collection of particles. (This is in contrast to kinetic energy, which is a measure of the energy carried by a single particle.) So, to answer a ...

Key Takeaways: Cocconi and Morrison's 1959 Nature paper, "Searching for Interstellar Communications," provided a foundational scientific framework for the then-unconventional field of SETI. The paper ...

JWST observations of Saturn's atmosphere revealed unprecedented details of its aurora and upper atmosphere, including previously unseen, complex structures. In the ionosphere (1100 km altitude), dark, ...

The universe's expansion means its size is bigger than its age suggests. The universe's expansion doesn't have a speed limit like objects within it. Distant galaxies move away from us as space itself ...

On September 20th, beginning around 12:30 A.M. EDT, Titan, a moon of Saturn, will transit across the planet's disk, accompanied by its shadow. The transit will be visible telescopically, with Titan's ...

Asteroid 2 Pallas, at 10th magnitude, exhibited a stationary position at 7:00 A.M. EDT within the constellation Aquila. Pallas's location was approximately 6.5° southeast of Altair, Aquila's brightest ...

As of March 2025, Saturn possesses 274 confirmed moons, the highest number among planets in the solar system. Early discoveries, beginning with Titan in 1655, were limited to five moons by the late ...

Data from NASA's Dawn mission, analyzed via thermal and chemical models, suggests Ceres possessed a long-lasting internal heat source driven by radioactive element decay. This heat source, reaching ...

Astronomers have discovered a lightweight black hole that’s a bit of a cosmic conundrum. Hypothetically, black hole masses can range all the way from far less than a paperclip to at least tens of ...

On a specified date, the Moon will pass 0.8° north of Venus and 1.3° north of Regulus (magnitude 1.4), with Venus and Regulus separated by less than 0.5°. This celestial trio will rise around 4:30 A.M ...

SpaceX's Starship Flight 9, though achieving orbit, failed due to a damaged pressurization system diffuser on the main fuel tank, leading to a chain of events including payload door failure and loss ...
