Dinosaurs evolved into some of the largest animals ever to walk the Earth, but a new mathematical model suggests that early mammals may have crowded them out of the ecological niches reserved for the smallest creatures.

A stunning new image from the NASA/ESA/CSA James Webb Space Telescope reveals a comet-shaped cloud in the Carina Nebula hiding a cluster of about 70 young stars, including a rare giant of O-type nearly 19 times as massive as the Sun.

Liquid Nitrogen May Have Flowed on Pluto’s Surface in Recent Past

10 August 2026 at 01:25
This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.

Planetary researchers analyzing images from NASA’s New Horizons spacecraft have found evidence that liquid nitrogen may still be seeping up from beneath the dwarf planet’s giant glacier, Sputnik Planitia, marking the first suggested case of recently flowing liquid on Pluto’s surface.

Inouye Solar Telescope Discovers Hidden Plasma Vortices on Sun

The highest-resolution image of the Sun’s surface (photosphere) ever captured, taken at 416 nm by the Inouye Solar Telescope; it reveals deformed boundaries of magnetic elements and ultra-fine scale stripes, both associated with Kelvin-Helmholtz instability. Image credit: NSF / NSO / AURA / MPS.

Astronomers using the 4-m Daniel K. Inouye Solar Telescope in Hawaii have detected tiny plasma vortices on the Sun’s surface (photosphere) for the first time, revealing a long-suspected process that could transport energy into the million-degree corona.

Dodo Had Surprisingly Keen Sense of Smell and Owl-Like Vision, New Study Reveals

The dodo (Raphus cucullatus) by Frederick William Frohawk, 1905.

New research led by University of Lethbridge scientists offers the most detailed look yet at how the dodo (Raphus cucullatus) -- the flightless bird driven to extinction by the 1600s -- actually perceived its world, suggesting the β€˜stupid bird’ had a far more complex sensory life than its reputation implies.

Moving Cat Indoors is Easier than Owners Expect: Study

Moving a free-roaming cat indoors for good is a decision many owners approach with dread: guilt over confining a former outdoor explorer, worry about litter boxes and scratched furniture, and doubts about whether the cat will ever adjust.

High-resolution images from ESO’s Very Large Telescope and the Large Binocular Telescope reveal that the E-type asteroid (44) Nysa may be unlike any other world in the Solar System, with three connected lobes and a newly discovered satellite that could help explain how the bizarre object formed.
