A rapidly intensifying low-pressure system off the coast is keeping the worst of the snow away from Boston, New York City and Washington, D.C.

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, makes us question the very existence of time – and how much we can manipulate it

The waxing gibbous Moon rises above Earth’s blue atmosphere in this photograph taken from the International Space Station as it orbited 263 miles above a cloudy Atlantic Ocean off the coast of Quebec, Canada.

Why is the Universe filled with matter? Why isn't it an equal amount of matter and antimatter? We still don't know the answer, but a new approach looks at the symmetries of extended models of particle physics and finds a possible path forward. It's a knotty problem that may just have a knotty solution.

Scientific American hosted an event at Morehouse School of Medicine to highlight medical advances in treating sickle cell disease and how far we still have to go

Two clashing ideas about disorder inside black holes now point to the same strange conclusions, and it could reshape the foundations of how we think about space and time

The microphone on NASA's Perseverance rover unexpectedly heard tiny claps of thunder from sparks caused by colliding dust grains.

The post Tiny Sparks of Lightning Detected on Mars for the First Time appeared first on Sky & Telescope.

The review was carried out and released by the Vaccine Integrity Project, which is dedicated to bolstering vaccines in the U.S.

Is there any science to viral relationship tests like the bird test, the orange peel theory and the moon phase test? Emily Impett, a professor of psychological and brain sciences at the University of Toronto, has the answers

Mathematics is not only an esoteric vocation but also indispensably alive and deeply human

Remember back in 2018 when there was a discovery of a briny “lake” underground near the Martian south pole? Pepperidge Farm probably does, and anyone that works there that’s interested in space exploration will be disappointed to hear that, whatever might be causing the radar signal that finding was based on, it’s most likely not a lake. At least according to new data collected by the Mars Reconnaissance Orbiter (MRO) and published recently in Geophysical Research Letters by lead author Gareth Morgan of the Planetary Science Institute and his colleagues.

Scientists found evidence of a distant planet’s moon system forming

On 2 December 1995 the ESA/NASA Solar and Heliospheric Observatory (SOHO) blasted into space – on what was supposed to be a two-year mission. 

From its outpost 1.5 million km away from Earth in the direction of the Sun, SOHO enjoys uninterrupted views of our star. It has provided a nearly continuous record of our Sun’s activity for close to three 11-year-long solar cycles. 

We knew from prior analyses that a distant asteroid sampled in 2020 carried all but one of the molecules needed to kick-start life, and researchers have just found the missing ingredient: sugar
