What is a quasar?

A quasar is an extremely bright and distant point-like source visible to radio telescopes. The source is a so-called Active Galactic Nucleus, fueled by a supermassive black hole.

Climate change projections show there may not be snow for skiing at some NH mountains by 2070 –

DURHAM — By the 2070s, if climate change continues at its current global warming pace, New Hampshire’s southernmost ski areas could see snowless winters that are so warm that they’ll be unable to even make snow for skiers and riders….

Amid global warming, why are we in a deep freeze? – The Daily Star

During winter, more often than not, a large part of northern United States is pummelled by an Arctic blast, sometimes severe, sometimes less severe, that lasts for a week or two. But this winter’s blast plunged not only the Midwest…

How Exactly Does Carbon Dioxide Cause Global Warming? – State of the Planet

“You Asked” is a series where Earth Institute experts tackle reader questions on science and sustainability. Over the past few years, we’ve received a lot of questions about carbon dioxide — how it traps heat, how it can have such…

Why does this galaxy look older than its years?

To the extent that we can see them, galaxies in the very early universe should look relatively young and unformed. But galaxy ALESS 073.1 is a surprise to astronomers: it looks more mature than we’d have any reason to expect. Why?

Tool that more efficiently analyzes ocean color data will become part of NASA program

(Stevens Institute of Technology) Researchers at Stevens Institute of Technology have developed a new machine learning-powered platform, known as OC-SMART, that can process ocean color in satellite images 10 times faster than the world’s leading platform. The work, which will be adopted by NASA, is one of the first machine learning-based platforms in ocean color analysis that can process both coastal and open ocean regions globally to reveal data on sea health and the impact of climate change.

Future ocean warming boosts tropical rainfall extremes

(Institute for Basic Science) Climate models predict that the difference between El Niño and La Niña related tropical rainfall will increase over the next 80 years, even though the temperature difference between El Niño and La Niña may change only very little in response to global warming. A new study uncovers the reasons for this surprising fact.

Steady now: Unfortunate timing and rate of change may be enough to tip a climate system

(University of Copenhagen – Faculty of Science) Unpredictable, abrupt changes to Earth’s system of ocean currents could commence from rate-induced tipping, model study shows. ‘The findings point to fundamental limitations inclimate predictability,’ authors warn.
