The heart of world’s largest solar telescope begins to beat

The world’s largest solar telescope, the U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope in Hawaii, has reached an important milestone. After almost 15 years of preparation, the German instrument for the Inouye Solar Telescope, the Visible Tunable Filtergraph (VTF), has now taken its first images. The imaging spectro-polarimeter was developed and built at the Institute for Solar Physics (KIS) in Freiburg (Germany). The Max Planck Institute for Solar System Research (MPS) in Göttingen (Germany) is a partner in the project.

The data published now were obtained during the technical commissioning of the instrument. VTF analyzes the sunlight captured by the Inouye Solar Telescope in more detail than ever before and, among other things, extracts information on the flow velocity of the solar plasma and the magnetic field strength at the visible surface of the Sun and in the directly adjacent gas layers above. Even in the current technical test phase, VTF is making smallest structures visible. In later scientific operation, when the data is extensively post-processed, the resolution will improve further.

With a primary mirror diameter of four meters, the Inouye Solar Telescope is the largest in the world. Thanks to the optimal observational conditions on the Hawaiian volcano Haleakala and the use of sophisticated methods of image stabilization and reconstruction, the Inouye Solar Telescope has been providing breathtakingly detailed views of our star since 2022: it can make smallest structures visible. To extract as much detailed information as possible about our star from sunlight, the Inouye Solar Telescope is gradually being equipped with additional scientific instruments. They process the incoming light, for example by examining individual wavelength ranges or polarization states of the light separately. Four of the five instruments are already in operation. The latest addition, the world’s largest spectro-polarimeter VTF, is the most powerful of them. As part of the technical commissioning, the first images of the Sun have now been taken with VTF.

NASA Just Got a Rare Look Inside Uranus — Here’s What They Found

A rare celestial alignment in April 2025 gave NASA scientists the chance to study Uranus in exceptional detail as it passed in front of a distant star. This stellar occultation, visible only from parts of western North America, allowed researchers to measure changes in Uranus’ atmosphere that hav

MIT physicists snap the first images of “free-range” atoms

MIT physicists have captured the first images of individual atoms freely interacting in space. The pictures reveal correlations among the “free-range” particles that until now were predicted but never directly observed. Their findings, appearing today in the journal Physical Review Letters, will help scientists visualize never-before-seen quantum phenomena in real space.

The images were taken using a technique developed by the team that first allows a cloud of atoms to move and interact freely. The researchers then turn on a lattice of light that briefly freezes the atoms in their tracks, and apply finely tuned lasers to quickly illuminate the suspended atoms, creating a picture of their positions before the atoms naturally dissipate.

The physicists applied the technique to visualize clouds of different types of atoms, and snapped a number of imaging firsts. The researchers directly observed atoms known as “bosons,” which bunched up in a quantum phenomenon to form a wave. They also captured atoms known as “fermions” in the act of pairing up in free space — a key mechanism that enables superconductivity.

Dancing Between Atoms and Galaxies: A Smooth Continuum of Scales

The notion that the quantum realm somehow sits sealed off from the relativistic domain has captured popular imagination for decades. Perhaps this separation is comforting in a way, because it assigns neat boundaries to a notoriously complex theoretical landscape. Yet, a careful look at both cutting-edge research and historical development suggests that no such invisible barrier actually exists. Early quantum pioneers such as Planck (1901) and Heisenberg (1925) laid foundations that seemed confined to the minuscule domain of atoms and subatomic particles. Before long, Einstein (1916) showed us that gravity and motion operate in ways that defy purely Newtonian conceptions, especially at cosmic scales. Despite the apparent chasm between the quantum and relativistic descriptions, threads of continuity run deeper than we once imagined. The famous energy discretization proposed by Planck was intended to solve classical paradoxes at microscopic scales, but the fundamental constants he unveiled remain essential at any size, linking the behavior of infinitesimal systems to grand cosmic events.

Modern experiments push this continuity further into the mainstream conversation. Quantum coherences documented in biological processes illuminate the reality that phenomena once labeled “strictly quantum” can permeate living systems in everyday environments (Engel et al., 2007). Photosynthesizing cells exploit wave-like energy flows, migratory birds appear to navigate using subtle quantum effects, and intriguing evidence suggests that neuronal microtubules might process information at scales once deemed too large for quantum behavior (Hameroff, 1998). If relativity reliably predicts how massive objects curve spacetime, and quantum theory demonstrates how particles and fields manifest as discrete excitations, then the missing piece in unifying these perspectives may hinge on the realization that neither domain is airtight. We stand on a continuum of phenomena, from photosynthetic molecules absorbing photons to astrophysical bodies warping spacetime.

Disk discovery changes views on star and planet formation

A study led by Paolo Padoan, ICREA research professor at the Institute of Cosmos Sciences of the University of Barcelona (ICCUB), is challenging the understanding of planetary disk formation around young stars.

The paper, published in Nature Astronomy, reveals that the environment plays a crucial role in determining the size and lifetime of these planetary disks, which are the sites of planet formation.

When a star forms, it is surrounded by a spinning disk of gas and dust. Over time, this material eventually forms the planets. Traditionally, scientists believed that once a disk forms, it simply loses too much over time as it feeds the star and the growing planets.

Astronomers Find Far-flung “Super Earths” Are Not Farfetched

A new study shows that planets bigger than Earth and smaller than Neptune are common outside the Solar System.

An international team including astronomers from the Center for Astrophysics | Harvard & Smithsonian (CfA) has announced the discovery of a planet about twice the size of Earth orbiting its star farther out than Saturn is to the sun.

These results are another example of how planetary systems can be different from our solar system.
