Almost 50 more genes have been flagged as being linked to Alzheimer’s, along with changes in activity in crucial cells that disappear as dementia progresses

Hurricane season is shaped by the ingredients needed to produce a tropical cyclone, and this year the Atlantic may be relatively quiet

A deadly Ebola outbreak is spreading fast—and U.S. cuts to foreign aid are making it worse

Two companies are aiming to preserve Arctic ice by pumping water onto the sheet and letting it freeze, but only one of the trials found that this delayed melting in the summer

This month’s episode highlights the close pairing of Venus and Jupiter under way in the western sky after sunset. You'll also learn why astronomers are fixated on a star in Corona Borealis — and how to find a huge but dim constellation that will likely be new to you. So grab curiosity and come along on this month’s Sky Tour.

The post June Podcast: Dance of the Planets appeared first on Sky & Telescope.

It’s 2234, you’re on your annual class field trip touring exoplanets, and your teacher informs everyone they can pick one more exoplanetary system to explore before heading back to Earth. You and your classmates are exhausted from the day’s activities and you’re hungry. However, you get really excited because you already know what everyone will want. You and your classmates all shout in unison, “The young and far away puffy ones!”

It’s June 2027, and you’re fresh off defending your PhD studying the direct imaging of exoplanets while starting your postdoctoral journey at NASA Jet Propulsion Laboratory. The trauma of eating ramen and living off a sub-living wage for the last five years of your life is still fresh in your brain. But you’re excited to finally get your real career started with funding you received for viewing time on the much-anticipated Nancy Grace Roman Space Telescope (Roman for short). You begin to download the first set of data as your eyes tear up knowing your entire journey in research and academia is about to be worth it.

It’s 2165, and methane is in high demand, especially after the Titan Treaty of 2145 made it illegal to harvest methane from Saturn’s moon, Titan. But the advent of interstellar travel has made exoplanetary exploration far easier, enabling corporations to identify and harvest methane from exoplanets. However, it’s far cheaper and easier to harvest methane from exoplanets with reasonable (also called temperate) temperatures, because it means higher quantities of methane. The Exoplanet Exploration Corporation decides to send its first ship to one such exoplanet loaded with methane that could bring their quarterly financial statements back into the green.

Before any spacecraft can survive the Moon, it has to survive something almost as brutal, a giant metal chamber in Houston that strips away every molecule of air and swings temperatures from scorching to freezing in minutes. Blue Origin's lunar lander just spent time in exactly that chamber and it came out the other side ready for the real thing.

We are closer than ever to detecting signs of life on another world. The James Webb Space Telescope is already ‘sniffing’ alien atmospheres, and the Habitable Worlds Observatory is being built specifically to find biology beyond Earth. But a new paper raises an uncomfortable question; when we do find that first biosignature, will it actually tell us anything meaningful about life in the universe? The answer, it turns out, might be no.

In recent decades, the Search for Extraterrestrial Intelligence (SETI) has seen a revival, and future surveys will benefit from new technologies. Similarly, our perception of what technologies an advanced civilization might use has expanded.

Every galaxy we know of spins. It's one of those rules of the universe so fundamental that astronomers barely think about it anymore. So when the James Webb Space Telescope pointed at one of the most massive galaxies in the early universe and found…well nothing. No spin, just stillness. They had to look twice.

For nearly thirty years, dark energy has been cosmology's great get out of jail free card, the invisible, mysterious force we invented to explain why the universe is expanding faster than it should be. Now a team of mathematicians says we may never have needed it at all. And the implications are stranger than you might think.

An early galaxy cluster named after an Indian lake is teaching astronomers about influences on galaxy evolution in the infant Universe. Astronomer Ronaldo Laishram of the National Astronomical Observatory of Japan (NAOJ) used the Subaru Telescope’s wide-field camera, Hyper Suprime-Cam (HSC), to conduct a large sky survey to look for early galaxies with active star formation. The result was the discovery of a massive protocluster of galaxies that existed some 12.6 billion years ago, very early in cosmic time. Detailed study of this region could give new insight into how galaxies and their clusters form and evolve.
