A vibrant infrared image of Jupiter. The planet is characterized by thick, horizontal blue and orange bands. Two prominent, glowing white oval storms-the Great Red Spot and a smaller companion-are positioned in the lower hemisphere. The poles and the edges of the planet glow with a saturated red-orange hue, highlighting the heat and atmospheric depth of the gas giant.

This week’s image is of our neighbor Jupiter! Gemini North’s NIRI with adaptive optics captured this IR view of Jupiter, highlighting features like the Great Red Spot in bluer tones than in optical wavelengths. Check out the 🧵 for more papers on hot Jupiters!

A heat map plot showing the relative probability of an exoplanet or companion’s mass versus its semi-major axis. The x-axis is labeled semi-major axis in Au, and the y-axis is labeled mass in Jupiter masses. A colorbar is on the right-hand side of the plot and indicates relative probability from 0.0 to 1.0. The plot shows a diagonal region of high relative probability in bright orange and yellow, surrounded by green contour lines. The probability decreases to purple and black at the edges.

A scatter plot displaying orbital eccentricity vs. orbital semi-major axis in Au. The plot shows the distribution of exoplanets (specifically Hot and Warm Jupiters) and the theoretical zones of their orbital evolution.

A multi-panel astronomical plot for the star SPLUS J2104-0049, showing its spectral energy distribution (SED) and imaging data. Top and Right Margins: A series of small, colored square thumbnail images showing the star at different wavelengths, ranging from ultraviolet (uJAVA) to near-infrared (zSDSS). Main Graph: A central plot of flux versus wavelength (in angstroms), ranging from 3,500 to 9,000 Angstroms. The spectrum: A jagged grey line representing the Gemini/GMOS spectrum, showing prominent absorption features like the CH G-band, Ca II H & K lines, and various Balmer lines. Photometry: Colored circles and squares represent narrow-band and broad-band flux measurements, labeled with their corresponding AB magnitudes. Filter Profiles: Large, overlapping, colored shaded regions at the bottom illustrate the transmission curves for the 12 different filters used in the S-PLUS survey.

If you took only a quick glance at this image, you might think that the dark patches occulting the stars were smoke, rising from the ground. In fact this dazzling image — taken on Maunakea, Hawai’i at the northern site of the international Gemini Observatory (right), a program of NSF NOIRLab — shows the Milky Way in vivid detail, allowing us to see not only the stars, but the dusty regions which block their light. Tiny flecks mostly inorganic matter make up cosmic dust which in turn forms enormous obscuring clouds. The dark, smoke-like trail through the heart of the Milky Way is one such cloud, known as the Great Rift, containing more mass than 1 million suns.
