Much have I travell’d in the realms of gold,

And many goodly stars and clusters seen;

Round celestial islands have I been

With telescope after telescope to the night sky hold.

Oft of one wide expanse had I been told

That Galileo ruled as his demesne;

Yet did I never breathe its pure serene

Till I heard Baade speak out loud and bold:

Then felt I like some watcher of the skies

When a new star cluster swims into his ken;

Through his majestic window looks upon the Milky Way

He star’d at the centre of our galaxy.… Continue reading.

A Speeding Pulsar, Martian Carbon and the first James Webb Science Images

with No Comments

Webb Observations Released – NASA released the first full-color images and spectra taken by the James Webb Space Telescope, that weren’t alignment or test images. The telescope operates in infrared, so for humans to be able to see Webb images, the wavelengths detected are shifted to visible light wavelengths such that they appear to be color images.… Continue reading.

The Sky Reborn

Ever since I read Bart J. Bok’s foreword to Rose Wilder’s and Gerald Ames’ The Golden Book of Astronomy, I have marveled at what the night sky had to offer and how much of that has changed. “Such wonders,” Bok wrote,” fill this book.”… Continue reading.

JWST Survives Micrometeoroid – NASA’s James Webb Space Telescope (JWST) team revealed that a micrometeoroid hit one segment of its primary mirror, causing a very slight degradation in its image. The impacting object was roughly the size of a dust particle, but still a bit larger than pre-launch estimates predicted should hit the mirror during the lifetime of the telescope.… Continue reading.

In the late summer of 1964 I was leaving the Observatory of the Royal Astronomical Society’s Montreal Centre with some friends, one of whom was David Zackon. I asked the group if they would like to drop by my house to observe with a 3.5-inch reflector.… Continue reading.

Pulsar Beams, Colliding Galaxies and a Misaligned Black Hole

FRB Source Located – Fast radio bursts (FRBs) are powerful flashes of radio energy that last only milliseconds, and what causes them is not understood. Some of them repeat from the same source, but many do not. A research team led by scientists at Chalmers University of Technology and the University of Amsterdam linked up twelve radiotelescope antennas around the world to obtain extreme location precision on one FRB repeater.… Continue reading.

Omicron!

Over the last few months you must have read dozens of articles, online or in print, about the Omicron variant of COVID-19. Fortunately, this is not one of them. This article is about Omicron² Eridani. It is a faint star in the constellation of Eridanus, the River.… Continue reading.
