Published Quest for alien signals in the heart of the Milky Way takes off



A graduate student is spearheading an extraordinary scientific endeavor -- a groundbreaking mission to uncover periodic signals emanating from the core of the Milky Way called the Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS). Such repetitive patterns could be the key to unlocking the mysteries of extraterrestrial intelligence in our galaxy.
Published Towering plume of water escaping from Saturn moon



Scientists have observed a towering plume of water vapor more than 6,000 miles long -- roughly the distance from the U.S. to Japan -- spewing from the surface of Saturn's moon, Enceladus.
Published Astronomers discover last three planets Kepler telescope observed before going dark



With the help of citizen scientists, astronomers discovered what may be the last three planets that the Kepler Space Telescope saw before it was retired.
Published 4,000-year-old plague DNA found -- the oldest cases to date in Britain



Researchers have identified three 4,000-year-old British cases of Yersinia pestis, the bacteria causing the plague -- the oldest evidence of the plague in Britain to date.
Published One-third of galaxy's most common planets could be in habitable zone



A third of the exoplanets orbiting common M dwarf stars have gentle enough orbits to potentially be in the habitable zone capable of hosting liquid water.
Published X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration



Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door to reimagining how particle acceleration works. One model of how jets generate x-rays expects the jets' x-ray emissions to remain stable over long time scales. However, the new paper found that the x-ray emissions of a statistically significant number of jets varied over just a few years.
Published Early toilets reveal dysentery in Old Testament Jerusalem



Study of 2,500-year-old latrines from the biblical Kingdom of Judah shows the ancient faeces within contain Giardia -- a parasite that can cause dysentery.
Published Astronomers discover a key planetary system to understand the formation mechanism of the mysterious 'super-Earths'



A study presents the detection of a system of two planets slightly larger than Earth orbiting a cold star in a synchronized dance. Named TOI-2096, the system is located 150 light-years from Earth. This system, located 150 light-years from Earth, is one of the best candidates for a detailed study of their atmosphere with the JWST space telescope.
Published Helium nuclei research advances our understanding of cosmic ray origin and propagation



The latest observations from Low Earth Orbit with the International Space Station provide further evidence of spectral hardening and softening of cosmic ray particles.
Published A deep underground lab could hold key to habitability on Mars



Tunnels deep underground in North Yorkshire are providing a unique opportunity to study how humans might be able to live and operate on the Moon or on Mars.
Published NASA's Hubble hunts for intermediate-sized black hole close to home



Astronomers have come up with what they say is some of their best evidence yet for the presence of a rare class of 'intermediate-sized' black hole that may be lurking in the heart of the closest globular star cluster to Earth, located 6,000 light-years away.
Published Eruption of Tonga underwater volcano found to disrupt satellite signals halfway around the world



Researchers found that the Hunga-Tonga eruption was associated with the formation of an equatorial plasma bubble in the ionosphere, a phenomenon associated with disruption of satellite-based communications. Their findings also suggest that a long-held atmospheric model should be revised.
Published An X-ray look at the heart of powerful quasars



Researchers have observed the X-ray emission of the most luminous quasar seen in the last 9 billion years of cosmic history, known as SMSS J114447.77-430859.3, or J1144 for short. The new perspective sheds light on the inner workings of quasars and how they interact with their environment.
Published Ancient climate change solves mystery of vanished South African lakes



New evidence for the presence of ancient lakes in some of the most arid regions of South Africa suggests that Stone Age humans may have been more widespread across the continent than previously thought.
Published Oldest architectural plans detail mysterious desert mega structures



Researchers have identified engravings in Jordan and Saudi Arabia as the oldest known scaled building plans in human history.
Published Humanity's earliest recorded kiss occurred in Mesopotamia 4,500 years ago



Written sources from Mesopotamia suggest that kissing in relation to sex was practiced by the peoples of the ancient Middle East 4,500 years ago.
Published Radio signal reveals supernova origin



Astronomers reveal the origin of a thermonuclear supernova explosion. Strong emission lines of helium and the first detection of such a supernova in radio waves show that the exploding white dwarf star had a helium-rich companion.
Published NASA's Spitzer, TESS find potentially volcano-covered Earth-size world



Astronomers have discovered an Earth-size exoplanet, or world beyond our solar system, that may be carpeted with volcanoes. Called LP 791-18 d, the planet could undergo volcanic outbursts as often as Jupiter's moon Io, the most volcanically active body in our solar system.
Published South Africa's desert-like interior may have been more inviting to our human ancestors



Lining the Cape of South Africa and its southern coast are long chains of caves that nearly 200,000 years ago were surrounded by a lush landscape and plentiful food.
Published Astronomers observe the first radiation belt seen outside of our solar system



Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images of persistent, intense radio emissions from an ultracool dwarf reveal the presence of a cloud of high-energy electrons trapped in the object's powerful magnetic field, forming a double-lobed structure analogous to radio images of Jupiter's radiation belts.
