There Could be as Many Water Worlds as Earths in the Milky Way
On July 12th, 2022, NASA released the first images acquired by the James Webb Space Telescope, which were taken during its first six months of operation. Among its many scientific objectives, Webb will search for smaller, rocky planets that orbit closer to their suns – especially dimmer M-type (red dwarf) stars, the most common in the Universe. This will help astronomers complete the census of exoplanets and gain a better understanding of the types of worlds that exist out there. In particular, astronomers are curious about how many terrestrial planets in our galaxy are actually “water worlds.”
SpaceX's Starlink internet service reaches Antarctica
SpaceX touts the ability of its Starlink satellite constellation to beam internet service to remote areas around the world, and it doesn't get much more remote than this.
Mars did Have Moving Glaciers, but They Behaved Differently in the Planet's Lower Gravity
On Earth, shifts in our climate have caused glaciers to advance and recede throughout our geological history (known as glacial and inter-glacial periods). The movement of these glaciers has carved features on the surface, including U-shaped valleys, hanging valleys, and fjords. These features are missing on Mars, leading scientists to conclude that any glaciers on its surface in the distant past were stationary. However, new research by a team of U.S. and French planetary scientists suggests that Martian glaciers did move more slowly than those on Earth.
The Tonga Eruption Produced a 90-Meter Tsunami
The gigantic underwater Tonga volcano eruption event captured the world’s attention in January of this year. People from around the world marveled at the satellite imagery of this awesome demonstration of nature’s destructive capability. But only now are we learning that the volcano triggered something else – a tsunami wave up to 90m tall, nine times higher than the tsunamis generated by earthquakes.
What is the gravitational constant?
What is the gravitational constant, how do scientists measure it, and is it really constant or can it change across time and space?
Dazzling imagery of supernova remnant holds clues about star's death (video)
Using data from NASA's Chandra X-ray Observatory, Hubble Space Telescope and recently retired Spitzer Space telescope, astronomers traced the timeline of a supernova explosion called SNR 0519.
Lost Moon Could Solve Saturn’s Riddles
An icy moon torn apart in Saturn's gravitational field some 150 million years ago could explain why the planet's rings are so young and a host of other puzzles.
NASA requests 2 new private astronaut missions to International Space Station
NASA requested proposals for two additional private missions to the International Space Station to run between late 2023 and 2024, adding on to others approved or already flown with Axiom Space.

Taking the dazzle out of CryoSat yields a first
Since it was launched more than 12 years ago, ESA’s CryoSat ice mission has dazzled by way of its sheer technological and scientific excellence. This superb Earth Explorer satellite has returned a wealth of information that has transformed our understanding of Earth’s ice and how it is responding to climate change. In some circumstances, however, being dazzled isn’t a good thing, particularly when it comes to measuring the height of sea ice from space during the summer.
