Scientists propose a new idea about why intelligent life hasn’t contacted humanity. A planet would need continents, oceans, and plate tectonics for a civilization to emerge in a galaxy.
James Webb telescope makes discovery that was previously impossible
Astronomers used the James Webb Space Telescope to view star clusters inside an ancient galaxy, under 500 million years after the universe formed.
The strange new worlds scientists have discovered this year
Astronomers are finding hundreds of exoplanets — worlds that don’t orbit the sun — each year. Here are some of the new 2024 discoveries.
Scientists spot massive asteroid collision — in another solar system
Astronomers used the James Webb Space Telescope to determine that huge asteroids collided in the distant solar system Beta Pictoris, located 63 light-years from Earth.
NASA reveals why it’s so hard to spot alien life — even with Webb
NASA exoplanet scientists explain how the James Webb Space Telescope looks for hints of life, and why it’s so challenging to find this evidence.
New Webb telescope image isn’t just stunning. It shattered a record.
Scientists used the James Webb Space Telescope to find the oldest-known galaxy ever found. It formed just 290 million years after the universe was created.
Scientists just found a really strange super-Earth
Astronomers used two powerful telescopes to find a rocky super-Earth orbiting extremely close to its host star. It’s called TOI-1798 c, and likely doesn’t have an atmosphere.
Scientists discovered a Venus-like world that might not be a hellhole
Two teams of scientists have discovered a so-called “exo-Venus” — similar in scale to Earth’s evil twin planet, but with a chance of being habitable, depending on its atmosphere.
New James Webb Space Telescope photo truly boggles the mind
Scientists used the James Webb Space Telescope to capture a deep field view of space, including a view of two early galaxies and their black holes colliding.
Scientists find Earth-sized planet. It’s orbiting a fascinating star.
Astronomers discovered an exoplanet about the size of Earth that’s orbiting an ultra-cool red dwarf, a star that can live over 100 billion years.
