A United Launch Alliance Atlas 5 rocket blasted off Friday and boosted a pair of prototype internet satellites into orbit for Amazon’s Kuiper program, the latest entry in the increasingly competitive space-based broadband market currently dominated by SpaceX.
The Draconid meteor shower will be active from Oct. 6 to Oct. 10, reaching its peak on Monday (Oct. 9) under a fairly dark moon.
According to some in the astrophysical community, there has been something of a “Crisis in Cosmology” in recent years. Though astronomers are all aware that the Universe is in a state of expansion, there has been some inconsistency when measuring the rate of it (aka. the Hubble Constant). This issue arises from the Cosmic Distance Ladder, where astronomers use different methods to measure relative distances over longer scales. This includes making local distance estimates using parallax measurements, nearby variable stars, and supernovae (“standard candles”).

A pair of Earth observation satellites along with ten auxiliary payloads will launch aboard Arianespace’s penultimate Vega rocket into sun-synchronous orbit on Friday. The light launch vehicle, which began flying in 2012, is set to liftoff from Europe’s Spaceport in French Guiana on Oct. 6 at 10:36 p.m. local time (9:36 p.m. EDT, 0136 UTC).
Back in the 70s, kids used to look up at the summer sky and try to be the first one to shout, “Satellite!” That seems like a relic from the past now, alongside Polaroid cameras and astronauts on the Moon. These days, it’s rare to spend any amount of time looking at the sky without seeing a satellite, or several of them.
The first two prototypes for Amazon's Project Kuiper satellite-internet constellation took flight today (Oct. 6), lifting off atop a United Launch Alliance Atlas V rocket.
Comet 12P/Pons-Brooks has awakened again from its recent slumbers with a fresh outburst. It's now bright enough to see in a modest telescope.
Celebrate the upcoming annular solar eclipse with a new app launched by Astronomers Without Borders. "One Eclipse" for iOS brings the wonders of the eclipse into the palm of your hand.
Namira Salim became the first person from Pakistan to reach space today (Oct. 6), a milestone she achieved on Virgin Galactic's 'Galactic 04' mission.
The first images from a new Earth-observing satellite reveal in unprecedented detail how temperature changes on the planet's surface.
The blast of light was 100 times brighter than an ordinary supernova, but it came from intergalactic space between two distant galaxies.
In 1840 an unassuming star in the Southern Hemisphere brightened suddenly. What had been a 5th magnitude star became so bright by 1843 that it was the second brightest star in the sky. The star, known as Eta Carinae, had been known to vary in brightness before, but this change was so sudden and so dramatic that it became known as the Great Eruption.
A Vega rocket will launch 12 satellites to orbit tonight (Oct. 6) on its first mission of the year, and you can watch the action live.
As students advance to higher and higher physics courses, they eventually learn that the simple Newtonian dynamics they learned about in early classes aren’t completely accurate models for understanding the universe. If things get too big or fast, they fall into the realm of relativity, or if they get too small, they get caught up in quantum mechanics. However, simple Newtonian dynamics does the trick for things ranging from how a baseball flies to how planets orbit the Sun.
Spanish company PLD Space plans to launch one of its rockets for the first time ever today (Oct. 6), and you can watch the action live.
Discover the observations of astronomer Francis Baily as he watched sunlight bead along the lunar limb during an 1836 annular eclipse.
Loki returns with a season premiere full of exposition and set-ups that still manages to make us care and remind us of the great times.
NASA is getting the Artemis 2 Orion spacecraft built while testing key activities that astronauts will perform on their way to the moon and back.
New research indicates that Mercury's thermal contraction was still occurring as recently as 300 million years ago.
