ASU is eager to host more 51 Pegasi b Postdoctoral Fellows. (We've had 4 in the past 3 years.) People focused on the Solar System (i.e., not exoplanets) are VERY ALLOWED. Happy to chat with anyone about this opportunity 🥳 www.hsfoundation.org/programs/sci...

I had a wonderful time speaking with @startswithabang.bsky.social and @luiswel.bsky.social about biosignatures, exciting sub-Neptune science, and why we should care about studying exoplanets! Check out our podcast episode here:

A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. The image focuses on a collection of interacting galaxies connected by delicate streams of stars. At top center lies a large elliptical galaxy that is dense and smooth, like a polished stone glowing with golden light. Like delicate spider silk or stretched taffy, these stellar bridges link the large elliptical to the few larger galaxies beneath, evidence of past collisions.

All throughout the image, thousands of galaxies gather in clusters or are spread throughout, like glittering gems strewn on a table. Some are sharp-edged and spiral, like coiled ribbons; others round and diffuse, like polished pebbles. Still others are just smudges of various colors against the black of space. The background is peppered with pinpoint stars in reds, yellows, and blues, crisp against the velvet black. A cosmic tapestry of glowing tan and pink gas clouds with dark dust lanes. In the upper right, the Trifid Nebula resembles a small flower in space. Its soft, pinkish gas petals are surrounded by blue gas, and streaked with dark, finger-like veins of dust that divide it into three parts. It radiates a gentle, misty glow, diffuse and soft like the warmth of breath on a cold hand. To the lower left, the much larger Lagoon Nebula stretches wide like a churning sea of magenta gas, with bright blue, knotted clumps sprinkled throughout where new stars are born. Both nebulae are embedded in a soft tan backdrop of gas that is brighter on the left than on the right, etched with dark tendrils of dust and sprinkled with the pinpricks of millions of stars.A sprawling, textured field of galaxies scattered across the deep black of space. It is filled with the delicate smudges and glowing cores of galaxies of many shapes, sizes and colors, as well as the bright multi-colored points of stars. To the lower left is a region filled with the hundreds of golden glittering gems of a distant galaxy cluster. In the foreground, below and right of center, two blue spiral galaxies look like eyes beneath the entangled mass of a triple galaxy merger in the upper right. A few bright blue points of foreground stars pierce the glittering tapestry.

Good to see Pica-Ciamarra, Madhu+ engage with our work and correct claims from last month. Following our recommendation to expand the model space, they now find: ‘No molecule reaches 2σ significance when allowing for an offset…’ 𝐍𝐨 𝐛𝐢𝐨𝐠𝐚𝐬𝐞𝐬 𝐚𝐟𝐭𝐞𝐫 𝐚𝐥𝐥! Sec. 4.4 arxiv.org/abs/2505.10539 🔭 #exoplanets

Just shared a new paper on the arXiv, led my @luiswel.bsky.social and me, on the challenges associated with detecting gases in exoplanet atmospheres. As the field pushes towards new and exciting opportunities, we thought it was time to talk about what it really means to “detect” something!
