"All moments past, present, and future, always have existed, always will exist."
On Earth, carbon can form millions of compounds, while silicon is largely stuck inside rocks. But elsewhere, silicon could form the basis of life.
A new study shows that the Bernardinelli-Bernstein Comet is much larger than previously thought — potentially the largest ever spotted.
Ingenuity is remarkable. But these 5 exploration ideas are revolutionary. Telescopes are our initial tools for revealing and studying foreign worlds. Hubble images of Mars, particularly around the regions with […]
From here on Earth, looking farther away in space means looking farther back in time. So what are distant Earth-watchers seeing right now?
A new model of the Antikythera mechanism reveals a "creation of genius."
Just say no to artist’s illustrations. This is what the Universe actually looks like. The Universe we observe often surpasses our greatest imaginings. This 20-year time-lapse of stars near the center […]
A conversation with an advanced alien species is likely to be simple and to take 1,000 years. It might also be dangerous.
Life finds a way — particularly if it has a moon.
Jupiter's mysterious auroral events are caused by vibrating waves of plasma.
We just observed the first ‘lunar formation’ in an exoplanetary system. This one image, above, is the first to show moons actively forming around a planet. This colourful image shows […]
