Space and astronomy
Space and astronomy stories from NASA, ESA, and observatories worldwide. Exoplanets, black holes, dark matter, and the search for life beyond Earth.
Dyson Swarms May Destroy Themselves Before We Find Them
Breakthrough Listen physicist Brian Lacki calculated why Dyson sphere megastructures may collapse in cascading collisions long before any civilization can detect them.
Do Other Planets Have Seasons? Why Earth's Are Rare
Earth's Moon prevents our axis from wobbling wildly, keeping seasons stable. Mars and Uranus show what happens without that protection.
'Oumuamua: The Interstellar Object That Changed Everything
'Oumuamua defied physics when it visited in 2017. Scientists have an answer now. And two more interstellar objects have followed.
Space Exploration's Robot-Human Partnership Takes Shape
As robots venture into environments no astronaut could survive, NASA develops humanoid machines to work alongside future space explorers.
Why Some Planets Have Moons and Others Don’t
A planet’s gravitational reach determines its moon count. Saturn wins big. Mercury never had a chance.
Is the Moon a Planet? The Definition Debate Explained
Whether the Moon qualifies as a planet depends on who you ask. The debate reveals how hard it is to draw lines between...
Voyager 1 Light Day: NASA's 15-Billion-Mile Computer Repair
Engineers at NASA's Jet Propulsion Laboratory fixed a corrupted memory chip aboard Voyager 1 from 15 billion miles away, restoring science data after...
Cosmology Update: Dark Matter and Cosmic Filaments
Today we read about dark matter and energy's roles in shaping cosmic structures, the accelerated expansion of the universe and the early formation...
Dyson Swarm Could Harvest the Sun in 31 Years
Dyson swarm math shows dismantling Mercury and using exponential self-replication could capture the Sun's total energy output in just 31 years.
Black Holes: What They Are, How They Work, and Why They Matter
Black holes warp space, trap light, and challenge the laws of physics. From Einstein's predictions to the first photograph, here is what we...
