Virgin Galactic's reusable space plane VSS Unity aced its fifth commercial mission today (Nov. 2), continuing the one-flight-per-month tempo the company began this spring.
When Alan Stern launches to space this week on Virgin Galactic's fifth commercial flight, he'll accomplish the goal of a lifetime. But it won't just be a joyride for Stern — he'll be working.
Reference The Andromeda galaxy is the most distant object in the sky that you can see with your unaided eye. It's also on a collision course with our Milky Way.
Reference The OSIRIS-REx asteroid-sampling mission delivered pieces of asteroid Bennu to Earth on Sept. 24, 2023, before moving on to study asteroid Apophis in 2029.
Reference How long it takes to get to Mars depends on several factors including planetary position and available technology.
Reference Roughly 80% of the mass of the universe is made up of dark matter, a material that scientists cannot directly observe. So why do scientists think it dominates?
Reference A red giant star is a dying star in the last stages of stellar evolution. Our own sun will turn into a red giant, expand and engulf the inner planets — including Earth.
Reference NASA's Perseverance rover isn't just exploring the Red Planet. The life-hunting robot will also help a little bit of Mars make it to Earth a decade or so from now, if all goes according to plan.
Reference NASA is the United States space agency and was founded in 1958 to do human and robotic exploration of the solar system and to study the universe as well.
Reference Tycho Brahe was a pioneering Danish astronomer from the 16th century whose data collection and discoveries changed the way scientists looked at the skies.
Reference Saturn has the most moons of any other planet in the solar system. Here we explore some of the 145 moons that orbit the ringed planet.
Reference Sir Isaac Newton invented calculus and explained optics. His most significant work involved forces and the development of a universal law of gravity.
A new supernova that burst into the night sky in May 2023 should remain visible in the Pinwheel Galaxy for some time, astronomers say.
Reference Black holes are real, they're some of the strangest objects in space. Discover what black holes are and how they form with our informative black hole guide.
Reference Albert Einstein's theory of general relativity is based on the idea that massive objects cause a distortion in space-time, which is felt as gravity.
Reference Delve into the life and theories of Stephen Hawking; one of the greatest theoretical physicists in history.
Reference The largest known star in the universe is UY Scuti, a hypergiant with a radius around 1,700 times larger than the sun.
Reference Olympus Mons rises 16 miles above the Martian surface, making it the solar system's tallest volcano.
reference Most stars are main sequence stars that fuse hydrogen to form helium in their cores - including our sun.
As Earth's iron core cools unevenly, the resulting whirls create a slow westward drift in a region of the magnetic field.
Reference NASA's Parker Solar Probe is on a mission to study the sun closer than ever before. Learn more about the fastest spacecraft to date in our solar probe guide.
