Jupiter feasted on baby planets to fuel growth Researchers constructed a model based on gravitational data from NASA’s Juno space probe and other sources to examine the core of Jupiter, finding its center is filled with planetesimals, baby planets that the massive giant used to fuel its own growth.

Kelp forests thriving in Patagonia’s cool waters Large kelp forests are thriving and healthy in Patagonia, according to a study the region’s cold spells are maintaining the 200-year-old forests along the coast of the southern end of South America. Researchers studied roughly 40 years of surface temperature data taken along the coastline and found that […]
Milky Way’s closest quasar brimming with radio emissions Using a newly developed technique known as “self-calibration,” a team of Japanese astronomers has captured revolutionary photos of the closest quasar to the Milky Way, revealing a soft band of radio emission in the quasar’s galaxy. “By applying the same technique to other quasars, we expect to […]
AI identifies viruses with high zoonotic potential Artificial intelligence identified viruses in the bunyavirus, rhabdovirus, filovirus and flavivirus families as the viruses most likely to spill over from animals to humans, and the platform may help researchers better estimate risks of zoonosis within viral families. The computer model also identified the Amazon River basin as […]
Somewhere between 250 million and 3 billion years ago, Venus’s temperate climate gave way to a runaway greenhouse state. New research reveals how such a scenario could well occur on Earth and possibly turn Earth into a Venus. Venus, Earth’s nearest neighbour and once-potential twin, is a hot mess. Surface temperatures average about 475 degrees […]
Martian meteorite suggests no life on Red Planet After examining the remnants of a meteorite knocked loose from Mars 1.3 billion years ago, scientists found the 725-gram rock had only trace amounts of exposure to hydrogen, almost certainly confirming there has not been life on the Red Planet. United Press International It’s our own fault […]
Aerosol pollution reduces Pacific’s storm activity Increasing aerosol pollution from China and India has had a cooling effect, leading to reduced storm activity in the Pacific Ocean in recent decades, according to a study that relied on computer simulations. As a result, as the governments of those countries aim to reduce aerosol pollution, they also […]
Data from Mars rover suggest presence of rare rock Scientists who studied images collected by a Mars rover say the planet may contain ignimbrite, a rare rock created by powerful volcanic eruptions. The presence of ignimbrite, also found on Earth, would suggest eruptions on Mars were more violent than thought. Space Robotic rat can handle […]
Lava creates dunes on surface of volcanic Jupiter moon Using observations from NASA’s Galileo spacecraft and complex mathematical simulations, researchers discovered new information about the mysterious dunes on the surface of Io, Jupiter’s third-largest moon. The dunes are formed not by wind as on Earth but by “effusive” lava streams from Io’s hundreds of active […]
Water may be hidden beneath Europa’s icy surface Beneath the 20-kilometer thick ice crust covering Jupiter’s Europa moon, researchers think an ocean awaits. Scientists studying the frozen surface of Greenland have determined Europa is similar enough that its hidden water store could host microbial life. Space Climate crisis leaves parts of world with 50% fewer […]
