Ripples in spacetime may have revealed 1st evidence of tiny black holes born in the Big Bang
1+ hour, 23+ min ago (436+ words) "These primordial black holes could account for a significant portion, if not all, of dark matter." Ripples in the very fabric of space and time called "gravitational waves" may have provided the first tantalizing evidence of tiny black holes born…...
In 1995, Robert Williams bet against the experts and pointed NASA's Hubble at empty sky
2+ hour, 23+ min ago (260+ words) I told him that I'm willing to fall on my sword," he later recalled. Williams wanted a dark, uncluttered region of sky, free from the glare of known bright objects; many advisers called it too risky. Williams bypassed them using…...

Giant planet defies what scientists thought possible about planet formation
5+ hour, 54+ min ago (833+ words) Researchers have identified that a giant planet orbiting a small red star has an atmosphere poorer in heavy elements than its host star. That reversal breaks a pattern seen across other giant planets and forces a rethink of how these…...
How the James Webb Space Telescope's infrared detectors actually work, why they almost didn't, and what their engineering lineage tells us about the limits of observation
4+ hour, 17+ min ago (239+ words) NIRCam uses ten of these detector arrays, each with 2048 " 2048 pixels, covering short-wavelength and long-wavelength channels plus wavefront sensing. The total pixel count across the near-infrared instruments is in the tens of millions. Every single one of those pixels had to…...
Astronomers finally spot vast hydrogen clouds that fueled early galaxies
4+ hour, 3+ min ago (523+ words) For decades, scientists believed the early universe was filled with enormous amounts of hydrogen gas'the basic ingredient needed to form stars. But proving this idea has been difficult, because hydrogen is almost invisible in space. Now, a major survey has…...
