Early Planetary Migration Can Explain Missing Planets

Credit: CanvaThe model represents a shortage of planets with masses between super-Earths and mini-NeptunesA new model that represents the interaction of forces acting upon newborn planets can clarify two puzzling observations that have repeatedly turned up among the over 3,800 planetary systems cataloged to date.One puzzle called the "radius valley" refers to the rarity...

JWST Spots the Tiniest Galaxy Outside Our Local Globe

The giant El Gordo galaxy cluster has been used to spot a tiny galaxy beyond it. Credit: NASA.The James Webb Space Telescope has glimpsed the tiniest galaxy outside our regional world-- and it is a thousand times much less huge than the Milky Way.The James Webb Space Telescope (JWST) has found the tiniest galaxy...

A Black Hole Spewed Out the Remains of One-Star Years After Consuming it

An artist's impression of the "burping" black hole. Credit: DESY / Science Communication Lab 3 years earlier, in October 2018, astronomers saw a black hole consuming and ripping one star apart in a galaxy 665 million light yrs away from Earth.Currently, just recently, the same astronomers observed the same black hole lighting the sky, despite the...

X-rays Have Been Spotted From Behind A Black Hole For the First Time Ever

Researchers observed bright flares of X-ray emissions. Image credit: Dan WilkinsResearchers at Stanford University have actually located a strange pattern while seeing the X-rays from the supermassive black hole at the centre of a galaxy 800 million light-yrs away. The black hole, it seems, is spewing out these rays into the universe around it.Dan...

The Perseids Meteor Shower is Back, but Not Exactly

A shower of Perseid meteors lights up the sky in 2009 in this NASA time-lapse image. Credit: NASA/JPLTypically bringing one of the most stunning yearly meteor showers visible in Earth's night sky, typically providing 50-100 "shooting stars" per hour at its peak, the Perseids are going to peak on Aug. 12 and 13. There...

James Webb Captures New Images of the Cartwheel Galaxy

Image of the Cartwheel Galaxy and its companion galaxies is a composite from Jame Webb’s Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI). MIRI data is colored red while NIRCam data is colored blue, orange, and yellow.Credit: NASA, ESA, CSA, STScIThe space telescope's powerful infrared gaze offers a new sight of just how the galaxy...

Potential Alien Sign Coming From an Earth-like Planet

But do not be too thrilled-- the researchers say it might easily just be a misidentified transmission from us humans.Credit: NASA.A group of Chinese and American researchers put their reputation on the line with a bold claim: that, with many caveats, a recently identified narrowband signal could indicate intelligent extraterrestrial life.The uncommon signal-- captured...

Astrophysicists Develop “Time Machine” Simulations To Observe the Lifecycle of Ancestor Galaxy Cities

Scientists create “time machine” simulations studying the lifecycle of ancestor galaxy cities. Credit: Scitech Daily.Scientists have produced simulations that directly recreate the complete life cycle of a few of the biggest collections of galaxies observed.Several processes in astrophysics take a very long time, making their evolution tricky to study. A star like our sun...

“Hyper Burst” Nuclear Explosion Observed for the First Time in a Neutron Star

Credit: techzle.Astronomers believe they have discovered proof for an incredibly powerful nuclear explosion in space-- one so unique that seeing one like it again is extremely unlikely.The explosion appears to have occurred inside an unusual neutron star found 140,000 light-years from Earth called MAXI J0556-- 332. Neutron stars are the remnant cores of bigger...
