Discovered in 1912, cosmic rays have been studied extensively and our current understanding of them is compiled into what is called the Standard Model. Recently, this understanding has been challenged by the detection of unexpected spectral structures in the cosmic ray proton energy spectrum. Now, scientists take this further with high-statistics and low-uncertainty measurement of these protons over a broader energy range using the CALorimetric Electron Telescope, confirming the presence of such structures.

Astronomers may have discovered the ancient chemical remains of the first stars to light up the Universe. Using an innovative analysis of a distant quasar observed by the 8.1-meter Gemini North telescope on Hawai'i, the scientists found an unusual ratio of elements that, they argue, could only come from the debris produced by the all-consuming explosion of a 300-solar-mass first-generation star.

Using the James Webb Space Telescope (JWST), researchers have identified the most distant globular clusters ever discovered. These dense groups of millions of stars may be relics that contain the first and oldest stars in the universe. The early analysis of Webb's First Deep Field image depicts some of the universe's earliest galaxies.

The first map of the 'galactic underworld' -- a chart of the corpses of once massive suns that have since collapsed into black holes and neutron stars -- has revealed a graveyard that stretches three times the height of the Milky Way, and that almost a third of the objects have been flung out from the galaxy altogether.

With electric vehicles sales soaring worldwide, potential buyers are not just weighing up the price tag, but also the logistics and expense of charging the planet-friendly cars. A new study shows households with solar panels and batteries will be the big winners.

Astronomers have assembled the largest-ever compilation of high-precision galaxy distances, called Cosmicflows-4.

As electric vehicles grow in popularity, the spotlight shines more brightly on some of their remaining major issues. Researchers are tackling two of the bigger challenges facing electric vehicles: limited range and slow recharging.

Using data from the Gaia space telescope, a team has shown that large parts of the Milky Way's outer disk vibrate. The ripples are caused by a dwarf galaxy, now seen in the constellation Sagittarius, that shook our galaxy as it passed by hundreds of millions of years ago.

Researchers offer a new mixture of metallic elements to serve as lithium-ion cathodes. This 'high-entropy doping strategy' is part of an effort to remove cobalt -- and expensive and geopolitically problematic mineral -- from LI batteries.

Astronomers have developed a new technique to identify small planets hidden in protoplanetary disks.

Astrophysicists show how and when specific particles form and offers clues to questions that have troubled scientists since the 1940s.

A new simulation conducted on the world's most powerful supercomputer dedicated to astronomy has produced a testable scenario to explain the appearance of the bar of the Milky Way. Comparing this scenario to data from current and future space telescopes will help clarify the evolution of our home Galaxy.

Of all known planets, Earth is as friendly to life as any planet could possibly be -- or is it? If Jupiter's orbit changes, a new study shows Earth could be more hospitable than it is today.

Early in its history, shortly after the Big Bang, the universe was filled with equal amounts of matter and 'antimatter' -- particles that are matter counterparts but with opposite charge. But then, as space expanded, the universe cooled. Today's universe is full of galaxies and stars which are made of matter. Where did the antimatter go, and how did matter come to dominate the universe? This cosmic origin of matter continues to puzzle scientists. Physicists have now opened a new pathway for probing the cosmic origin of matter by invoking the 'cosmological collider.'

Stars are the machines that sculpt the universe, yet scientists don't fully know how they form. To understand the frenzied 'baby boom' of star birth that occurred early in the universe's history, researchers turned to the Small Magellanic Cloud, a satellite galaxy of the Milky Way. This nearby galaxy has a simpler chemical composition than the Milky Way, making it similar to the galaxies found in the younger universe, when heavier elements were more scarce. This allows it to serve as a proxy for the early universe. Two separate studies -- the first with the Hubble Space Telescope, and the second with the European Southern Observatory's Very Large Telescope -- recently came to the same conclusion. Using different methods, the independent teams found young stars spiraling into the center of a massive star cluster called NGC 346 in the Small Magellanic Cloud. This river-like motion of gas and stars is an efficient way to fuel star birth, researchers say. The teams' results show that the process of star formation in the Small Magellanic Cloud is similar to that in our own Milky Way.

A new study suggests that many more planets may have large amounts of water than previously thought--as much as half water and half rock. The catch? All that water is probably embedded in the rock, rather than flowing as oceans or rivers on the surface.

Astronomers have just announced the discovery of two 'super-Earth' planets orbiting LP 890-9, a small, cool star located about 100 light-years from Earth.
