Could Primordial Black Holes Be Hiding in Plain Sight?

03-12-2024 20:54 via universetoday.com

Are Primordial Black Holes real? They could’ve formed in the unusual physics that dominated the Universe shortly after the Big Bang. The idea dates back to the 1960s, but so far, the lack of evidence makes them purely hypothetical.If they do exist, a new paper suggests they may be hiding in places so unlikely that nobody ever thought to look there.Black holes form when massive stars reach the end of their lives and suffer gravitational collapse. However, Primordial Black Holes (PBHs) didn&

NASA Wants Students’ Help Designing Missions to Other Moons

03-12-2024 20:04 via universetoday.com

One of NASA’s primary missions is to inspire the next generation of scientists and engineers to join the STEM field. It does so by producing inspirational and educational content on various platforms. But sometimes, it takes a more direct approach by rewarding students for their contributions to solving a particular problem NASA is facing. Recently, the organization announced such a challenge – the Power to Explore Challenge, which is open to submission from K-12 students until the e

Antarctica Has Gotten 10 Times Greener in 35 Years

03-12-2024 18:19 via universetoday.com

Our satellites are dispassionate observers of Earth’s climate change. From their vantage point they watch as pack ice slowly loses its hold on polar oceans, ice shelfs break apart, and previously frozen parts of the planet turn green with vegetation.Now, scientists have compiled 35 years of satellite data showing that Antarctica is slowly, yet perceptibly, becoming greener.
NASA and the United States Geological Survey sent the first Landsat into space in 1975. Since then, they’ve lau

White Dwarfs Could Have Habitable Planets, Detectable by JWST

03-12-2024 17:28 via universetoday.com

In a few billion years, our Sun will die. It will first enter a red giant stage, swelling in size to perhaps the orbit of Earth. Its outer layers will be cast off into space, while its core settles to become a white dwarf. Life on Earth will boil away, and our planet itself might be consumed by the Sun. White dwarfs are the fate of all midsize stars, and given the path of their demise, it seems reasonable to assume that any planets die with their sun. But the fate of white dwarf planets may not

Now is the time to catch Jupiter at its best.The King of the Planets rules the winter night skies. Early December gives sky watchers a good reason to brave the cold, as Jupiter shines at its best. Look for the regal planet rising in the east at sunset, while the Sun sets to the west.Why Opposition?For an outer planet, we call this point ‘opposition’ as the planet sits ‘opposite’ to the Sun from our Earthly perspective. This also means that Jupiter is above the horizon for

Nieuwe kaart van het heelal maakt gebruik van zwaartekrachtgolven

03-12-2024 08:50 via astronieuws.nl

Een internationaal onderzoeksteam onder leiding van astronomen van de Swinburne University of Technology (Australië) heeft de meest detailrijke kaarten van kosmische zwaartekrachtgolven tot nu toe gemaakt. Het onderzoek heeft ook de grootste galactische zwaartekrachtgolfdetector ooit opgeleverd en nieuwe aanwijzingen opgeleverd voor een ‘achtergrond’ van zwaartekrachtgolven: onzichtbare maar ongelooflijk snelle rimpelingen in de ruimte die kunnen helpen bij het ontsluieren van e

Dragonfly is Going to Titan on a Falcon Heavy

03-12-2024 00:57 via universetoday.com

NASA has given SpaceX the contract to launch the Dragonfly mission to Saturn’s moon Titan. A Falcon Heavy will send the rotorcraft and its lander on their way to Titan in 2028, if all goes according to plan, and the mission will arrive at Titan in 2034. Dragonfly is an astrobiology mission designed to measure the presence of different chemicals on the frigid moon.
Dragonfly will be the second craft to visit Titan, along with the Huygens probe and its short visit back in 2005.Titan is remar
