How quickly could rabbits multiply if nothing stopped them? The answer is surprising and is a question that has intrigued mathematicians for centuries. Italian mathematician Leonardo Fibonacci was reflecting on the reproductive potential of rabbits as early as 1201. In his Book of Calculations, he explored how a population could grow from a single pair, … Read more
In July 2020, a gigantic Arctic shelf collapsed in Canada, losing more than 40% of its surface in just two days. The Milne Ice Sheet acted like a dam, trapping a layer of fresh water over the Arctic Ocean. A few months after its dissolution, that freshwater lake flowed into the ocean and disappeared completely. … Read more
The crater, named in honor of the late Thomas McGetchin, former director of the Lunar and Planetary Institute in Houston, is three times larger than the previous record found by the LRO a decade ago. Pockmarked since ancient times, the moon has some of the largest impact craters in the solar system, including one that … Read more
Russia today (September 16) launched a cargo mission to the International Space Station, delivering the cargo spacecraft to orbit for a three-day rendezvous trip. The Progress 96 robotic spacecraft lifted off on a Soyuz rocket from the Russian Baikonur Cosmodrome in Kazakhstan today at 9:33 a.m. EDT (1333 GMT). From the ignition of the engine … Read more
It’s 5:52 a.m. at Moynihan Train Hall. I’m balancing a bowl of fruit and my water bottle in one hand while tightening the straps of a backpack that’s carried by two laptops with the other. It’s the start of my twice-weekly commute between New York City and Washington, DC. I’m five months into this super … Read more
NEWYou can now listen to Fox News articles! Scientists in North Dakota recently discovered what researchers believe is the first known footprint left by an adult T. rex, preserving the predator’s footprints some 66.5 million years after it walked the Earth. The findings, which focused on footprints discovered near Marmarth, North Dakota, were published September … Read more
Una colisión lo suficientemente poderosa como para romper una luna helada en una nube de escombros parece, a primera vista, ser una forma eficiente de formar un océano. El impacto convierte el movimiento en calor. La gravedad une las piezas. La luna reconstruida debería comenzar su segunda vida con hielo más cálido y tal vez … Read more
A narrow ribbon next to an ultra-diffuse galaxy has become the strongest evidence yet for a globular cluster stellar stream beyond the Milky Way. The feature appears in deep Hubble images of UGC 9050-Dw1, a faint galaxy about 115 million light-years away, and extends from a compact object that is likely the cluster that is … Read more
Astronomers did not continuously film 3C 345’s jet for 27 years. They observed it 116 times between 1995 and 2022, then used a neural representation to infer a changing radio image consistent with those irregular measurements. The work appears in the peer-reviewed Nature article Video reconstruction of variable VLBI observations with neural fields, led by … Read more
The rings around a strange small body orbiting between Saturn and Uranus look eerily different from previous views, new observations from the James Webb Space Telescope (JWST) suggest. The rings surround Chariklo, which is a centaur, a strange type of object that shows characteristics of both asteroids and comets. Chariklo is only about 400 miles … Read more
