Diagnosing Neptune's Chilly Summer - Eos

Diagnosing Neptune’s Chilly Summer – Eos

Usually, when a planet heads into its summer months, the air tends to warm up, a direct consequence of sunlight shining more directly on the planet’s atmosphere. But according to an extensive analysis of Neptune’s atmosphere, the opposite phenomenon happened as the planet’s southern hemisphere progressed through midsummer. Infrared images showed that over the course …

James Webb is about to take us to the “edge of time”. Here’s why that’s even cooler than it sounds

“From a tropical rainforest to the edge of time itself, James Webb begins a voyage back to the birth of the Universe” – so went the launch narration when astronomy’s latest superpowered space explorer, the James Webb Space Telescope (JWST), lifted off from French Guiana on Christmas Day. Like most launch announcements, it employed a …

In Some Places, Black Holes are Tearing Apart Thousands of Stars at a Time

In Some Places, Black Holes are Tearing Apart Thousands of Stars at a Time

At the heart of the more massive galaxies in the Universe, there are supermassive black holes (SMBHs) so powerful that they outshine all of the stars in their galactic disks. The core regions of these galaxies are known as Active Galactic Nuclei (AGN), or by their more popular-moniker “quasars.” The ongoing study of these objects …

The instability at the beginning of the solar system MSUToday

The new trigger The idea started with a conversation Raymond and Jacobsen had back in 2019. They theorized the gas giants may have been set on their current paths because of how the primordial gas disk evaporated. That could explain how the planets spread out much earlier in the solar system’s evolution than the Nice …

2 giant marsquakes rock the far side of Mars

2 giant marsquakes rock the far side of Mars

NASA’s marsquake-hunting lander has detected its two largest seismic events to date — and on the far side of the planet, no less. NASA’s Insight lander touched down on Mars in November 2018 carrying the most sensitive seismometer ever designed. Since the mission’s arrival, it has detected countless events dubbed marsquakes, using the signals to …

Eating insects and 'cultured' milk could reduce human impact on the planet by 80%

Eating insects and ‘cultured’ milk could reduce human impact on the planet by 80%

Swamping lamb for crickets could help save the planet. (Getty) Switching to a diet of steaks grown in labs and burgers made from ground-up insects could reduce pressure on the planet by up to 80%, researchers say. The benefits of switching to these ‘novel or future’ foods (NFFs) could see big reductions in carbon emissions …
