Arctic precipitation rates to double as temperatures rise, finds new study

The Arctic is often cited for a plethora of impacts resulting from anthropogenic climate change, including glacier retreat and reductions in floating sea ice, meltwater incursions changing ocean salinity, as well as sea level ...

Zero-boil-off tank experiments to enable long-duration space exploration

Do we have enough fuel to get to our destination? This is probably one of the first questions that comes to mind whenever your family gets ready to embark on a road trip. If the trip is long, you will need to visit gas stations ...

Optically trapped quantum droplets of light can bind together to form macroscopic complexes

Condensed matter systems and photonic technologies are regularly used by researchers to create microscale platforms that can simulate the complex dynamics of many interacting quantum particles in a more accessible setting. ...

A black hole discovery could force us to rethink how galaxies came to be

Peering deep into the infancy of the universe, the European Southern Observatory's Very Large Telescope (VLT) recently confirmed the discovery of the brightest and fastest growing quasar. Quasars are luminous objects in the ...

Even if we can't see the first stars, we could detect their impact on the first galaxies

For a long time, our understanding of the universe's first galaxies leaned heavily on theory. The light from that age only reached us after traveling for billions of years, and on the way, it was obscured and stretched into ...

How could laser-driven lightsails remain stable?

It's a long way to the nearest star, which means conventional rockets won't get us there. The fuel requirements would make our ship prohibitively heavy. So an alternative is to travel light. Literally. Rather than carrying ...

Scientists reveal how tar particles from wildfire smoke absorb and refract solar radiation, light in atmosphere

Days after a wildfire, a type of smoke can linger in the atmosphere that contains tiny, brown, light-absorbing particles known as tar balls. These particles are believed to have a significant impact on Earth's radiative balance, ...

2023 was the hottest year in history—and Canada is warming faster than anywhere else on earth

In 2015, most countries, including Canada, signed on to the Paris Climate Agreement which set the objective of "holding the increase in global average temperature to well below 2 C above pre-industrial levels and pursuing ...

Uncertainty abounds in seeding the sky to fight climate change, says study

As greenhouse gas levels increase in Earth's atmosphere, scientists are considering ways to temporarily limit rising temperatures. One idea is to inject aerosols into the stratosphere to reflect incoming sunlight, thereby ...

Study explores the properties of a faint tidal disruption event

Using a spectral synthesis code designed to simulate conditions in interstellar matter, astronomers have explored a faint tidal disruption event (TDE) designated iPTF16fnl. Results of the study, published Dec. 29 on the pre-print ...
