Dr. James Daly of Astronomy for Change presents a public lecture on the Breakthrough Starshot Initiative that, if successful, will see the launch of humanities first interstellar mission. Thousands of nano-class, gram-mass scale robotic craft will be launched via a high-power, phased-array microwave laser to 20% the speed of light towards the nearest star system[…]

In this video, Dr. Jim Daly of Astronomy For Change discusses the early August Night Sky with some of the jewels of the Summer Sky, some of the prominent constellations, the Milky Way, the major planets visible (Jupiter & Saturn), the phases of the moon for August 10 – 13 along with the Perseid Meteor[…]
The object discussed in this article, Terzan5, was featured as the Astronomy Picture of the Day, APOD for 21 September, 2016 Astronomy Picture of the Day In a few articles I’ve touched upon a poorly understood class of objects known as Globular Clusters. These objects and the stars in them are galactic relics, timeposts that[…]
In this video, Dr. Jim Daly of Astronomy For Change revisits the Perseid Meteor Shower and takes a look at the stunning view looking south for Friday, August 9, 2019. We present new objects to view with binoculars or an amateur telescope, discuss the phase of the moon for August 8 and 9 and take[…]
In this video, we take a quick look at the early August sky at twilight and move on, later into the night, taking a look at the major planets (Jupiter and Saturn, in Scorpio and Sagittarius, respectively), a quick look at the early Autumn constellations, rising much later into the night. We then take an[…]
