An illustration of an iceberg on the sea, with the top half of the image showing the iceberg above the surface and the bottom half showing it below. The iceberg below the surface is larger than what can be seen from the surface and is depicted as a crystal with shimmering nodes and an iridescent interior. The region above the surface is bright and the surface below is dark with a few solitary floating bubbles. A small submarine with a white symbol of an atom floats near the base of the iceberg in the bottom right corner.
A graph with m [GeV] on the x-axis and q on the y-axis. It depicts new limits on the terrestrial density, nχ, of room-temperature millicharged particles recast from past Cavendish experiments. These are shown as blue shaded regions, labeled according to the assumed value of nχ. Shown in gray are previous limits from accelerators and SN1987A, as well as limits from ion traps for several representative densities shown in solid cyan.
Three-panel scientific figure illustrating variations in the Moon's crustal thickness. Panel (a) shows a global color-coded map of the lunar surface, with warm and cool colors indicating regions of thinner and thicker crust. Major features, including Mare Imbrium, Mare Humboldtianum, the South Pole–Aitken (SPA) basin, Apollo landing sites, Chang'e-7, and a proposed lunar facility (FSS), are labeled. Panel (b) presents a simplified map of crustal thickness with contour lines labeled in kilometers, highlighting broad regions where the crust is relatively thick or thin. Panel (c) shows a circular cross-sectional view of the Moon's crust, with the uneven surface and crustal thickness color-coded around the circumference. Labels identify the lunar surface, the bottom of the crust, Mare Imbrium, Mare Humboldtianum, and the SPA basin. A color scale indicates crustal thickness ranging from approximately 10 to 50 kilometers.

Schematic of the model used in the study in χeff-χp space.χeff, or effective inspiral spin, is on the horizontal axis and χp, or effective precessing spin, is on the vertical axis. A small blue-shaded circle centered near the origin represents first-generation mergers, defined by its means (µeff,p) and standard deviations (σeff,p) in both dimensions. A larger blue-shaded arch spanning a wider range of spin values represents higher-generation mergers and is determined by a characteristic spin (χc), characteristic mass ratio (qc), and Gaussian width perpendicular to the curve (𝜎).

Infographic titled "Quantum mechanics with only real numbers?" explaining that quantum mechanics can be reformulated using only real numbers by changing how multiple quantum systems are combined. The graphic compares the standard formulation, which uses complex numbers to describe quantum states, with an equivalent real-number formulation that represents each complex number as a pair of real numbers. Diagrams illustrate the different mathematical rules used to combine systems, emphasizing that the modified rule produces the same physical predictions as standard quantum mechanics. A summary at the bottom explains that no imaginary numbers are needed, calculations take place in a larger real-number space, and experimental outcomes remain unchanged.
Histogram comparing the distribution of environmental change rates and species adaptation rates. Blue bars show the probability distribution of relative environmental change rates on a logarithmic scale, while an orange bell-shaped curve represents adaptation rates. The two distributions largely overlap and are centered near a relative rate of 1, illustrating the study's finding that the range of species adaptation rates is similar to the range of extreme environmental change rates. Axes are labeled “relative rate” (x-axis) and “probability” (y-axis).

A heat map displaying intensity across a two-dimensional grid. The vertical axis represents '$a$' in micrometers, and the horizontal axis represents tau ($\tau$) in $k\sigma$. Three distinct, flame-like peaks rise from the bottom axis, centered horizontally at about 50, 140, and 220. A color scale on the right indicates intensity, ranging from 0 in dark burgundy up to 2 billion in bright white. Each peak has a wide, intense white and yellow base below 10 micrometers that tapers upward into a darker red point as height increases.

Scientific figure showing properties of binary white dwarf (WD) systems as a function of the masses of the two stars. The horizontal axis shows the mass of the primary white dwarf (M₁) and the vertical axis shows the mass of the secondary white dwarf (M₂), both ranging from about 0.1 to 1.4 solar masses. Colored contour regions indicate the expected gravitational wave frequency at Roche lobe overflow, with darker purple colors representing lower frequencies and orange colors representing higher frequencies. Additional colored shading across the upper portion of the plot represents binary system properties related to the combined mass of the pair. Several overlaid curves mark theoretical thresholds for stability, instability, and disk-direct accretion, along with projected sensitivity limits for the proposed MAGIS Space and AEDGE gravitational wave observatories. A dotted black line marks the Chandrasekhar mass limit.

A high-resolution astronomical visualization depicts a black hole centered within a dense, vibrant field of red, blue, and gold stars. The central event horizon is a perfect black void, surrounded by a dramatic "Einstein ring" where the gravity of the black hole warps and stretches the light of background stars into luminous, concentric arcs. While the stars at the edges of the frame appear as sharp pinpoints, those closer to the center are increasingly distorted into circular streaks, creating a powerful sense of gravitational suction and cosmic scale.
