SpaceX launched its third Falcon 9 rocket in less than 24 hours, bringing all three of its launch pads into play.
Even JWST can’t separate these tiny planets from their host stars – as they orbit their stars too closely. But there is a way to “see” the planet’s atmosphere from this entangled light.
The Large Magellanic Cloud is a small galaxy, just a tenth of the Milky Way’s mass. It is about 160,000 light years away, which is remarkably close in cosmic terms. In the southern hemisphere it spans the width of 20 Moons in the night sky. While the galaxy seems timeless and unchanging to our short human lives, it is, in fact, a dynamic system undergoing a near collision with our galaxy. Now astronomers are beginning to observe that process.
Back in 2007, I talked with Rob Manning, engineer extraordinaire at the Jet Propulsion Laboratory, and he told me something shocking. Even though he had successfully led the entry, descent, and landing (EDL) teams for three Mars rover missions, he said the prospect of landing a human mission on the Red Planet might be impossible.
Episode 1 of HBO's new "Dune" prequel miniseries, "Dune: Prophecy" introduces the secret history of the powerful Bene Gesserit sisterhood.
The Hubble Space Telescope may have captured our Milky Way galaxy being a bit of a bully.
One of the surprise findings with the James Webb Space Telescope is the discovery of massive galaxies in the early Universe. The expectations were that only young, small, baby galaxies would exist within the first billion years after the Big Bang. But some of the newly found galaxies appear to be as large and as mature as galaxies that we see today.
Marking a major milestone in the preparation of Copernicus Sentinel-1C for its scheduled 3 December liftoff, experts have completed the critical and hazardous process of fuelling the satellite.

SpaceX is preparing to launch a Falcon 9 rocket with a payload that has been shrouded in secrecy to the point of not disclosing any specifics of the mission, and not using its original name.
SpaceX is set to launch 20 more of its Starlink internet satellites from California's Vandenberg Space Force Base early Monday morning (Nov. 18).
We have been spoiled over recent years with first the Hubble Space Telescope (HST) and then the James Webb Space Telescope (JWST.) Both have opened our eyes on the Universe and made amazing discoveries. One subject that has received attention from both is the derivation of the Hubble Constant – a constant relating the velocity of remote galaxies and their distances. A recent paper announces that JWST has just validated the results of previous studies by the Hubble Space Telescope to accurately measure its value.
SpaceX is set to launch a satellite for the Australian telecom company Optus this afternoon (Nov. 17) from Florida's Space Coast.
The Breakthrough Starshot program aims to cross the immense distances to the nearest star in just decades. Using a high-powered laser to propel a reflective sail technology to relativistic speeds is their mission. The selection of sail material is key to its success as it must be lightweight while being able to withstand acceleration and radiation from the laser. A recent study explores various materials and proposes that core-shell structures—spherical particles composed of two different materials—could be a promising solution.
The only way to see the curve of the Earth is to fly more than 6 miles (10 kilometers) above its surface.
The Earth has always been bombarded with rocks from space. It’s true to say though that there were more rocks flying around the Solar System during earlier periods of its history. A team of researchers have been studying a meteorite impact from 3.26 billion years ago. They have calculated this rock was 200 times bigger than the one that wiped out the dinosaurs. The event would have triggered tsunamis mixing up the oceans and flushing debris from the land. The newly available organic material allowed organisms to thrive.

A company aiming to bring cell service to unmodified smartphones using a satellite network announced Thursday it had secured its ability to reach low Earth orbit.
Five varieties of heirloom seeds from the Choctaw Nation of Oklahoma were flown to the International Space Station last year and will be compared to Earth-bound seeds when planted this coming spring.
"At a time like this, we need to find more stories from the days when Americans outsmarted the bad guys and planted our flag on the moon."
RALEIGH, N.C. — Particle physicist Hitoshi Murayama admits that he used to worry about being known as the “most hated man” in his field of science. But the good news is that now he can joke about it.
We are all familiar with the atmosphere of the Earth and part of this, the ionosphere, is a layer of weakly ionized plasma. It extends from 50 to 1,500 km above the planet. It’s a diffuse layer but sufficient to interfere with satellite communications and navigation systems too. A team of researchers have come up with an intriguing idea to utilise millions of mobile phones to help map the ionosphere by relying on their GPS antennas.
