New radio images from ALMA show for the first time the direct effect of volcanic activity on the atmosphere of Jupiter's moon Io.
Three decades after Cornell astronomer Carl Sagan suggested that Voyager 1 snap Earth's picture from billions of miles away - resulting in the iconic Pale Blue Dot photograph - two astronomers now offer another unique cosmic perspective: Some exoplanets - planets from beyond our own solar system - have a direct line of sight to observe Earth's biological qualities from far, far away.
By combining photonics with artificial intelligence, University of Sydney scientists have developed a sensor that will help decipher the 'twinkle' of stars and allow for Earth-based exploration of planets around distant stars. Their invention will be deployed in one of the world's largest telescopes at Mauna Kea, Hawaii.
Astrophysicists have discovered a series of telltale shell-like formations of stars in the vicinity of the Virgo constellation, evidence of a radial merger between a dwarf galaxy and the Milky Way, and the first such 'shell structures' to be found in the Milky Way.
For anthropologists and other social scientists, the space race in the 1950s served as a period of cultural and technological transformation as well as an opportunity to advance the public good.
In the search to discover the origins of our solar system, an international team of researchers, including planetary scientist and cosmochemist James Lyons of Arizona State University, has compared the composition of the sun to the composition of the most ancient materials that formed in our solar system: refractory inclusions in unmetamorphosed meteorites.
In a study first published Aug. 5 in The Astrophysical Journal Letters, University of Texas at Dallas scientists demonstrated the first use of a method called self-calibration to remove contamination from gravitational lensing signals. The results should lead to more accurate cosmological models of the universe.
Astronomers at the University of Iowa have determined our galaxy is surrounded by a clumpy halo of hot gases that is continually being supplied with material ejected by birthing or dying stars. The halo also may be where matter unaccounted for since the birth of the universe may reside. Results published in the journal Nature Astronomy.
A new method for mapping the location and size of trees growing outside of forests helped scientists discover billions of trees in arid and semi-arid regions and lays the groundwork for more accurate global measurement of carbon storage on land.
The 'SAINT-EX' Observatory, led by scientists from the National Centre of Competence in Research NCCR PlanetS of the University of Bern and the University of Geneva, has detected two exoplanets orbiting the star TOI-1266. The Mexico-based telescope thus demonstrates its high precision and takes an important step in the quest of finding potentially habitable worlds.
