In August 2013, the Dark Energy Survey (DES) began its six-year mission to map thousands of galaxies, supernovae, and patterns in the cosmic structure. This international collaborative effort is dedicated to investigating the mysterious phenomenon known as Dark Energy. This theoretical force counter-acts gravity and accounts for 70% of the Universe’s energy-mass density. Their primary instrument in this mission is the 570-megapixel Dark Energy Camera (DECam), mounted on the Victor M. Blanco 5-meter (16.4 ft) telescope at the Cerro Tlelolo Inter-American Observatory in Chile.

Dimorphos grows a tail. More Europa pictures from Juno. The horrifying possibility of ads in the night sky. Why Jupiter’s atmosphere is surprisingly hot.

On September 26, 2022, leaks were discovered in the underwater Nord Stream 1 and 2 gas pipelines, located near Denmark and Sweden. Both pipelines are owned by Russia and were built to transport natural gas from Russia to Germany through the Baltic Sea. Officials have said the leaks were caused by deliberate action, not accidents, and were likely intentional sabotage. While accusations have abounded, the motives behind the damage are not yet known.

In a recent study, a collaborative team of researchers discuss the potential for future lunar settlers to establish a backup data storage system of human activity in the event of a global catastrophe on Earth that could be used to recover human civilization on a post-catastrophe planet. This comes as NASA’s Artemis missions plan to send people back to the Moon for the first time since 1972, coupled with current global events such as the ongoing coronavirus pandemic and the War in Ukraine, with Russian President Vladimir Putin recently threatening nuclear war. Given the current state of world affairs, how important is it to establish a type of off-world data backup?

What’s better than a pair of galaxies observed by a pair of iconic space telescopes? The answer to that, according to researchers using the Hubble and James Webb Space Telescopes, is finding even more galaxies and other remarkable details no one expected in the duo’s observations.

We know what will happen to our Sun.

One of the central predictions of general relativity is that a massive object such as a star, galaxy, or black hole can deflect light passing nearby. This means that light from distant objects can be gravitationally lensed by objects closer to us. Under the right conditions, gravitational lensing can act as a kind of natural telescope, brightening and magnifying the light of distant objects. Astronomers have used this trick to observe some of the most distant galaxies in the universe. But astronomers have also thought about using this effect a little closer to home.

It’s only natural to look at the Moon and wonder what it would be like to live there. Thanks to Buzz Aldrin who landed there in 1969, we know it’s a magnificent desolation. Even before the Apollo missions science fiction writers and scientists knew how desolate the place was. But, as far back as the late 19th Century, they also saw it as a natural outpost. So did NASA, the former Soviet Union, and their respective militaries. And, that led to people on both sides drawing up elaborate plans for Moon bases.

According to the predominant cosmological model, the first stars in the Universe formed roughly 100,000 years after the Big Bang. Known as Population III stars, these early stellar masses were very large, short-lived, and contained virtually no metals or heavier elements. Over time, elements like carbon, nitrogen, oxygen, and iron formed in their interiors through nucleosynthesis. When these stars reached the end of their lifespans, they exploded in a supernova many times greater than anything we see today (a “super-supernova”), causing these elements to be dispersed throughout the cosmos.

A new crew is on the way to the International Space Station, and the crew is a true and hopeful reflection of the international nature of the station. Commander Nicole Mann become the first Native American woman in space, and she is joined by JAXA (Japan Aerospace Exploration Agency) astronaut Koichi Wakata and Roscosmos cosmonaut Anna Kikina, as well as pilot and NASA astronaut Josh Cassada.

It’s been over twenty-two years since we’ve been able to see Jupiter’s enticing moon Europa close-up. But now the Juno spacecraft has made its closest pass of Europa, sending back some amazing pictures of the icy mini-world, which likely has an ocean that contains more water than all of Earth’s oceans combined.

Science fiction is the realm where people traditionally wrestle with the idea of contact with an ETI (Extraterrestrial Intelligence.) But now, those discussions are migrating from science fiction into more serious realms. Academics are going back and forth, one paper at a time, concerning the response and geopolitical fallout from potential contact with an ETI.

Commercial space company Firefly Aerospace successfully launched its Alpha rocket for the first time last weekend, reaching orbit and deploying three satellites. While the latest determination of the satellites’ orbit reveals they may have not been placed in the correct orbit, the company appears to consider the orbit high enough to be considered a success.

Recent climate research, published in the Nature Climate Change journal has confirmed that melting icecaps in Greenland will contribute a minimum of 27cm rise in ocean levels even if we collectively stop burning fossil fuels immediately. We have reached a “point of no return”. And what makes it worse is that this is the most conservative estimate, as it only factors the contribution made by the ice shelf in Greenland. Projections have also confirmed that overall planetary warming has exceeded the original estimates for global heating, and that we are in for a difficult millennium if drastic action isn’t taken immediately.

When planning crewed missions to Mars, the key phrase is “follow the water.” When astronauts set down on the Red Planet in the next decade, they will need access to water to meet their basic needs. Following the water is also crucial to our ongoing exploration of Mars and learning more about its past. While all of the water on the Martian surface exists as ice today (the majority locked away in the polar ice caps), it is now known that rivers, lakes, and an ocean covered much of the planet billions of years ago.

The Light Italian CubeSat for Imaging of Asteroids (LICIACube) has returned a series of close-up images of the asteroid Dimorphos, after last week’s successful impact of the Double Asteroid Redirect Test (DART) probe. LICIACube was built and operated by the Italian Space Agency (ASI), and was designed to capture post-impact imagery for the DART team, to help assess the effects of the impact.

More images and details keep coming in about the asteroid intentionally smashed by NASA’s Double Asteroid Redirection Test (DART) spacecraft last week, and this latest image is stunning.

NASA and NOAA satellites — as well as astronauts on the ISS — captured some stunning imagery of Hurricane Ian, as seen from orbit. Our lead image shows an eerie view of the hurricane’s eye on September 28. The Landsat 8 satellite passed directly over Ian’s eye as the storm approached southwest Florida.

Ancient impacts played a powerful role in Earth’s complex history. On other Solar System bodies like the Moon or Mercury, the impact history is preserved on their surfaces because there’s nothing to erase it. But Earth’s geologic activity has erased the evidence of impact craters over time, with some help from erosion.

We hope this is just as inconsequential as having a piece of toilet paper stuck to your shoe, but images from the Ingenuity helicopter show it had a piece of debris fluttering from its leg during its most recent flight. A blog post from NASA said a small piece of foreign object debris (FOD) was seen in footage from the Mars helicopter’s navigation camera (Navcam) for a portion of its 33rd flight on September 24, 2022.

Everything dies in the end, even the brightest of stars. In fact, the brightest stars are the ones that live the shortest lives. They consume all the hydrogen they have within a few million years, then explode as brilliant supernovae. Their core remains collapse into a neutron star or black hole. These small, dark objects litter our galaxy, like a cosmic graveyard.
