Using data and imagery obtained with the JWST, a recent study claims the universe is now 26.7 billion years old. We will unequivocally show that the age of the universe is still 13.77 Gyr. One of the principal reasons the JWST mission was conceived in the first place was to test existing theories and current[…]
Composite Image Produced from Two Flagship Orbiting Observatories At 32 million light years, this image of the Grand Design spiral galaxy, M-74 appears in this composite rendition using JWST and Hubble data. The JWST component includes data in the 2, 3 and 3.6 micron range. The Hubble component includes 435 nm, 555 nm, 656 nm[…]
The tiny red dot at the center of this image is our galaxy of interest, z13.1,13.1 billion light years distant. Heavy Element Nucleosynthesis, the process by which heavy elements are synthesized in the cores of high-mass stars, was ongoing in this galaxy less than 700 million years after the big bang. Note: this video is[…]
Today we look at the sky for the week beginning Sunday, July 25th. With this edition of the sky tonight, the sky has changed somewhat since last week. In the morning, Mercury is in Cancer with the sun and lost in the solar glare before sunrise. The evening sky sees Venus remaining prominently placed with[…]
With this edition of the sky tonight, the sky has changed slightly since last week. Today we look at the sky for the week beginning Sunday, July 18th. Sunday, July 18th, we have brilliant Venus and ruddy red Mars still well placed in the Southwest sky and setting at 9:50 PM, EDT, following the sun[…]
With this edition of the sky tonight, the sky has changed slightly since last week’s premier installment of our weekly sky tonight program.

By James Daly, Ph.D NASA Video at foot of article NASA Hubblesite news release here On the occasion of the Hubble Space Telescope’s 31st successful year in orbit last Saturday (4/24, launch date: 4/24/1990), the iconic orbiting telescope was tasked with capturing AG Carinae, a blue supergiant star in the southern constellation of Carina. This[…]
A quick video showing the placement of the Virgo Cluster of galaxies with the massive elliptical galaxy Messier-87 at its center. Imaged with the Hubble Space Telescope, M-87 is shown here surrounded by thousands of globular star clusters. Our Milky Way galaxy, a member of the Local Cluster of Galaxies is, in turn, a member[…]
This is the second part in the two part series showcasing and explaining the amazing physics and technology that made NASA’s latest mission to Mars such a resounding success. In the first video Dr. Daly explains the physics behind the launch and cruise phases of the mission, complete with explanations, diagrams, theory and calculations specific[…]
Join Dr. Jim Daly of Astronomy for Change as he showcases and describes a rare triple conjunction of Mercury, Jupiter and Saturn in the early morning hours before sunrise, a planetary alignment visible through Sunday, March 14. Those who are early risers will be witness to this rare planetary alignment. Especially rare and quite spectacular[…]
Link to video below With this video, Dr. Jim Daly of Astronomy For Change presents Part 1 of a multi-part series on the amazing physics and technology behind the brilliant journey and successful landing of the Mars2020 Perseverance Rover.
