Rare meteorite provides evidence of giant early planet
Rare meteorite provides evidence of giant early planet Stephanie Baum Scientific Editor Robert Egan Associate Editor Four-and-a-half billion years ago, a massive world—possibly as big as the moon or even Mars—orbited our sun before crashing into another celestial body and shattering into rubble. Now, in a paper published in the journal Earth and Planetary Science Letters, scientists report the first definitive evidence that this lost planetary embryo (protoplanet) existed. Its unique...
Atmosphere survival model refines search for habitable planets
Atmosphere survival model refines search for habitable planets Gaby Clark Scientific Editor Robert Egan Associate Editor Researchers have developed the Smaller Than Earth Habitability Model (STEHM) to assess which planets can maintain life-supporting atmospheres, focusing on size and atmospheric dynamics. Since 1992, NASA has confirmed the existence of over 6,000 planets outside of our solar system, and over 7,000 suspected planets still await confirmation. These distant planets, dubbed...
Wildfires reverse decade of ozone cleanup in the United States, study reveals
Wildfires reverse decade of ozone cleanup in the United States, study reveals Sadie Harley Scientific Editor Robert Egan Associate Editor Ozone pollution has worsened in much of the continental United States over the past decade, fueled by wildfires and the long-distance transport of unhealthy air, according to a new study titled "Fires reverse progress toward ozone air quality standards in the U.S.," led by University of Iowa researchers and published in the journal Science. Exposure to...

Stonehenge Altar Stone's epic transportation across ancient Britain detailed in new study Robert Egan Associate Editor New research by Curtin University has revealed how one of Stonehenge's most mysterious stones was likely transported hundreds of kilometers across Britain through challenging terrain, highlighting the remarkable capabilities of ancient communities. Stonehenge's central Altar Stone is a six-tonne sandstone megalith now believed to have originated in northeast Scotland, around...
'This is actually taking a page out of the Communist Party playbook': New White House proposal could deny scientists funding based on their political opinions
'This is actually taking a page out of the Communist Party playbook': New White House proposal could deny scientists funding based on their political opinions "It replaces expertise with political appointees, globally decouples the U.S. and completely guts our scientific ecosystem." The White House has proposed massive changes to the scientific process in the U.S. which, if passed, could make science funding dependent on the whims of political appointees. The Office of Management and Budget...
Astronomers measure the mass of a dormant black hole, our solar system's lost protoplanet, and more science stories
Astronomers measure the mass of a dormant black hole, our solar system's lost protoplanet, and more science stories This week's science news. It's been an eventful week in science news. Astronauts on the ISS were briefly ordered to shelter in place after the discovery of an air leak in the transfer tunnel, NASA officially declared its MAVEN space probe dead and scientists announced the creation of a "universal vaccine" designed by AI.
Meteorite found in Sahara desert may be 1st evidence of lost solar system world
Meteorite found in Sahara desert may be 1st evidence of lost solar system world "It points to a distinct and separate evolutionary path in planetary formation in the early history of our solar system." A rare meteorite recovered from the Sahara Desert contains the first definitive evidence of a long-lost world that may have rivaled the moon in size and existed just a few million years after the solar system formed 4.5 billion years ago, according to a new study. The meteorite, known as...

June 1, 2026 report One of our planets may be missing, and it could explain why the solar system looks the way it does Paul Arnold Author Sadie Harley Scientific Editor Robert Egan Associate Editor Our solar system has two ice giants, Uranus and Neptune, but there may have been a third. According to a new study published in the journal Icarus, this extra world might have triggered a violent planetary shuffling billions of years ago that could have disrupted some of Jupiter's and Uranus's...
