How a sunset would appear on other planets is a staple of science-fiction. The sun is as fundamental to grounding our existence as the earth, for most of us. Yet lots of people go months without seeing a sunrise or sunset.

That's extreme, but even more extreme is how it would look on Titan. 

I did not think I would need to explain here things that should be obvious to any sentient being, but the recent activity I detect on Facebook and other sites, and the misinformation spread by some science popularization sources and bloggers around the conclusions reached last week by the European Strategy Update for Particle Physics (EUSUPP), a 2-year-long process that saw the participation of hundreds of scientists and the heavy involvement of some of our leading thinkers, forced me to change my mind.

Environmental groups believe that living in cities is better for the environment but if there is one thing that COVID-19 has made clear, it's that living in cities is better for spreading infectious disease also. 

Despite having numerous large cities, the U.S. was on the verge of having measles wiped out, but as the anti-vaccine movement spread on the east and west coasts, they brought a resurgence of it. A group of researchers looked for its origins and found it may help provide answers about coronavirus, which is in the same family as the common cold but was discovered to be novel in the 1960s.

Though we've only detected a few thousand exoplanets, there are likely 6,000,000,000 Earth-like ones out there, and that means millions could be "ocean worlds" capable of supporting life.

Right now, our knowledge of ocean worlds is limited to moons like Enceladus around Saturn and Europa around Jupiter. Plumes of water erupt from Europa and Enceladus, so we can tell that these bodies have subsurface oceans beneath their ice shells, and they have energy that drives the plumes, which are two requirements for life as we know it

When called on to explain why he lives in a gigantic mansion with its resulting environmental cost, Academy Award winner, Nobel laureate, and U.S. Vice-President Al Gore said he bought carbon offsets from a company he owned that sold carbon offsets.

Paying himself to emit greenhouse gases sounded ridiculous but a new analysis shows that buying offsets - paying a company to plant trees - can be just plain risky. 

Forests absorb carbon dioxide from the atmosphere, but if they are managed by a group that doesn't believe in logging or clearing brush. If a forest goes bust in a fire all that stored carbon goes up in smoke again.

There have been more celebrity suicides during the COVID-19 pandemic and while tragic, they may help to bring great awareness to the risks of depression and anxiety in other populations at all times. Such as pregnant and postpartum women.

Pluto, along with many other dwarf planets in the outer solar system, is often thought of as dark, icy and barren – with a surface temperature of just −230°C.

But now a new study, published in Nature Geoscience, suggests that the body has had a warm interior ever since it formed, and may still have a liquid, internal ocean under its icy crust.

It could mean that other sizable icy dwarf planets may have had early internal oceans too, with some possibly persisting today. This is exciting, as where there’s warm water, there could be life.

How did the continents form? It's a complex question, and no firm answers will be coming soon, but the oceanic plateau of the Kerguelen Islands may provide part of the answer, according to a new paper.

From a geological point of view, it is the Earth's outermost layer that distinguishes the continents from the oceans: oceanic crust, which is relatively thin, is mainly made up of basalts, resulting from the melting of the Earth's underlying mantle, whereas continental crust, which is thicker and of granitic composition, is derived from magmas that evolved at depth before solidifying.

Netflix is the big name in streaming, virtually everyone who has any interest in digital shows has heard of them, but they still give you a free trial.

No matter your size, and even if it's an existing customer, it makes good business sense, finds a new paper.

The last three years have been a banner time for environmental crisis hyperbole, especially when it comes to reporting about insects and agriculture.
