Earth’s ‘mini moon’ to disappear for 30 years | Science, Climate & Tech News
admin
A so-called “mini moon” that has been floating round Earth for two months will soon disappear. The harmless space rock, which scientists say could be a boulder that was blasted off the actual moon, was first spotted in August. Known as 2024 PT5, the rock began to partially circle Earth in a horseshoe-shaped path in…

‘Mini-moon’ about to enter Earth’s orbit and stick around for months | Science & Tech News
admin
The moon will get a companion this week as an asteroid around the length of a double-decker bus enters Earth’s orbit. The temporary guest, called 2024 PT5, should arrive on 29 September and is expected to befriend the regular moon for around two months. “A mini-moon is a small object orbiting another solar system body,”…

Late-phase solar flares could be more dangerous for Earth’s communication than thought, new study suggests | Science & Tech News
admin
Later-stage solar flares could be more disruptive to communication systems than previously thought, according to new research. While it’s well known the first wave of a solar flare – a sudden burst of energy from the Sun – can knock out GPS signals and trigger global radio blackouts, the secondary emission is less-studied. A new…

First UK military spy satellite launched that captures daytime images of Earth’s surface | UK News
admin
The first UK military satellite which can capture daytime images and videos of the Earth’s surface has successfully launched into space. The “cutting-edge” satellite – named Tyche – is part of a Ministry of Defence (MoD) programme that aims to support military operations as well as natural disaster and environmental monitoring, mapping information development, and…

Human-driven climate change has ‘slowed the Earth’s rotation’ and could affect how we measure time, study suggests | Science & Tech News
admin
The melting of polar ice due to human-driven climate change has slightly slowed the Earth’s rotation – and it could affect how we measure time, according to a study. Although the disappearance of the ice has reduced the speed of the planet’s rotation, the Earth is still spinning a bit faster than it used to.…

Doomed Peregrine moon lander to be allowed to burn up in Earth’s atmosphere, says Astrobotic | World News
admin
The spacecraft which attempted the first US moon landing in more than 50 years is to be allowed to “burn up” during re-entry into Earth’s atmosphere, the company behind the mission has said. Pittsburgh-based Astrobotic said it had made the “difficult decision” to maintain the craft’s trajectory and was working with NASA and the space…

HOTSAT-1: ‘World’s thermometer’ sends back first pictures of Earth’s hotspots in ‘milestone for climate monitoring’ | Science & Tech News
admin
A British-built “flying thermometer” has sent back its first pictures from space of hotspots on Earth. High-resolution thermal images taken by the satellite HOTSAT-1 reveal the sun-baked streets of Las Vegas, a vast oil storage complex in Oklahoma and the intense heat of the Canadian wildfires. HOTSAT-1, which has been dubbed “the world’s thermometer”, was…

Earth’s inner core may have stopped spinning as part of seven-decade cycle, say scientists | World News
admin
The spinning core at the centre of Earth may have recently stopped rotating, relative to the surface, as part of a seven-decade cycle, scientists have said. A study said the inner core, which is the size of Pluto, could have stopped spinning around 2009. This could be possible because the inner core is mostly a…

Winchcombe meteorite boosts theory regarding origins of Earth’s oceans | Science & Tech News
admin
A new study of a meteorite that landed in Winchcombe has bolstered a theory regarding the origins of water on Earth. Scientists have published their first detailed analysis of the carbonaceous chondrite meteor, which fell on the Gloucestershire town in February 2021. The new study, published in Science Advances, shows that carbonaceous chondrites like the…

Earth’s ‘black hole police’ discover gravitational singularity near Milky Way | Science & Tech News
admin
An international team of astronomers known as the “black hole police” have discovered a dormant black hole located right next to the Milky Way. The team, including Kareem El-Badry of the Harvard-Smithsonian Centre for Astrophysics – himself nicknamed the “black hole destroyer” – is famed throughout the astronomy community for debunking new discoveries of gravitational…
