We can’t see the first stars yet, but we can see their direct descendants
If you take a Universe worth of hydrogen and helium, and let it stew for about 13 billion years, you get us.
We are the...
Solar sails could reach Mars in just 26 days
A recent study submitted to Acta Astronautica explores the potential for using aerographite solar sails for traveling to Mars and interstellar space, which could...
Galaxies breathe gas, and when they stop, no more stars form
For most of the history of astronomy, all we could see were stars.
We could see them individually, in clusters, in nebulae, and in fuzzy...
This exoplanet is probably a solid ball of metal
We can’t understand nature without understanding its range.
That’s apparent in exoplanet science and in our theories of planetary formation. Nature’s outliers and oddballs put...
Scientists create a recipe book to search for alien life
Have you ever wondered if there's life on other planets?
Scientists at the University of Wisconsin–Madison are asking the same question, but they've taken an...
Helicopters could map the magnetic fields on Mars
A recent study published in The Planetary Science Journal examines how helicopters equipped with a magnetometer could be used to conduct magnetic field investigations...
A collision between gigantic galaxy clusters. Too big, too early
Just when cosmologists have a workable theory for when and how galaxy collisions happened in the early Universe, something challenges it.
In this case, the...
When did the first continents appear in the universe
On Earth, continents are likely necessary to support life.
Continents ‘float’ on top of the Earth’s viscous mantle, and heat from the planet’s core keeps...
Why we can’t predict what’s happening around the Milky Way’s black hole
Ever wonder what's going on at the heart of our galaxy?
Well, scientists are always trying to figure it out too.
Researchers in the Netherlands and...
