Take a Fantastic Flight Through a Stellar Creche

Celebrating 25 Years with Another Great Image This is what you get when scientists peer into the heart of a starbirth region: lots of hot young stars, radiating ultraviolet light and blasting out strong winds that are eating away at the leftovers of their birth cloud. The still image of this is amazing, but when you

HST's 25th Anniversary and Documentary

This week marks the 25th anniversary of the launch of the Hubble Space Telescope. This Wednesday night, PBS will be featuring a documentary, Invisible Universe Revealed which will look at the history of this amazing instrument. I'm looking forward to seeing this documentary, not just because I love the HST, but because a post I wrote in 2007 that mentioned the Hubble caught the attention of those working on the documentary. In particular, I noted that the HST added tremendously to our unders

So it Could be a Supervoid' That's Causing the Mysterious CMB Cold Spot'

Only last month I recorded a DNews video about the awesome possibilities of the “Cold Spot” that sits ominously in the cosmic microwave background (CMB) anisotropy maps (anisotropies = teenie tiny temperature variations in the CMB). I still hold onto the hope that this anomalous low temperature region is being caused by a neighboring parallel […]

100,000 Galaxies, and No Obvious Signs of Life

Beam us up, Scotty. There's no signs of intelligent life out there. At least, no obvious signs, according to a recent survey performed by researchers at Penn State University. After reviewing data taken by the NASA Wide-field Infrared Survey Explorer (WISE) space telescope of over 100,000 galaxies, there appears to be little evidence that advanced, […]

astro anecdotes

there are all sorts of astronomy folklore stories passed down through generations of astronomers. did you know that the 107'' telescope at McDonald observatory has bullet holes in the primary mirror? Six bullet holes in the primary mirror of the 2. 7m telescope at McDonald Observatory. Photo credit: McDonald Observatory. I used to observe with that telescope all the time during my PhD and it was always fun to walk down the solid tube to see the "damage" up close. the six holes only b

what kills a galaxy?

or maybe a more appropriate title is "how do you know when a galaxy is officially old?" Anyway, I wrote an article for the conversation with astronomers Tanya Hill and Sarah Brough describing some new research on how galaxies stop forming stars. Giant galaxies die from the inside when they stop making starsGalaxy clusters are impressive but do they hinder star formation?

Dawn Rises Over Ceres North Pole

Brand new images taken on April 10 by NASA's Dawn probe show the dwarf planet from high above its north pole. Photographed at a distance of just 21,000 miles (33,000 km) less than 1/10 the Earth-moon distance ┬they're our sharpest views┬to date. The crispness combined with the low-angled sunlight gives Ceres a stark, lunar-like […]

Firefly Astronomy

Light makes life, and sometimes, life returns the favor. There's nothing more magical than watching fireflies flit across a starlit field on a summer's night. Growing up in Northern Maine, summer was an all-too swiftly passing season, and fireflies had to put on their displays in a brief profusion of frenzied activity around late July […]

Beyond Fermi's Paradox II: Questioning the Hart-Tipler Conjecture

It's become a legend of the space age. The brilliant physicist Enrico Fermi, during a lunchtime conversation at Los Alamos National Laboratory in 1950, is supposed to have posed a conundrum for proponents of the existence of extraterrestrial civilizations. If space traveling aliens exist, so the argument goes, they would spread through the galaxy, colonizing […]

How to present science to anyone

This article is originally published for Inspiring Australia in early April 2015. Giving a presentation is your opportunity to share your passion about a topic with an audience and empower them to wonder "why?" about the same questions that fascinate you. When the audience walks away with a deeper understanding of something you've convinced them is important, they will remember you and what you gave to them. Communicating complex science ideas does not come naturally to everyone, but is a
