Trump going back on promises I’m beginning to suspect that we’ve been conned by our new president. He’s backpedaling on nearly every campaign promise he made to us...

This Christmas, think before you speak Now that Trump has won the election, a lot of folks who call themselves Christians seem to believe they have a mandate to force their beliefs on the rest of us. Think about doing this before you start yelling about people saying “happy holidays,” whining about Starbucks coffee cup image(s), complaining about other’s lifestyles…

First Amendment protects prayer (Re: Atheist Gary Singer’s contribution to the Crossed column titled “What will it take to make America great again?” in the Nov. 21 edition of Northern Express.) Mr. Singer, the First Amendment states: “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof …”

Evidence of global warming Two basic facts underlay climate science: first, carbon dioxide was known to be a heat-trapping gas as early as 1850; and second, humans are significantly increasing the amount of CO2 in Earth’s atmosphere through the burning of fossil fuels and other activities. We are in fact well on our way to doubling the CO2 concentrations in our atmosphere...

Other community backpack programs I just read your article in the Nov. 28 issue titled “Beneficial backpacks: Two local programs help children.” It is a good article, but there are at least two other such programs in the Traverse City area that I am aware of...

A ‘fox’ in the schoolhouse Trump’s proposed secretary of education, Betsy DeVos (“the fox” in Dutch), is a right-wing billionaire; relentless promoter of unlimited, unregulated charter schools and vouchers; and enemy of public schooling...

Eye in the Sky: Hubble Space Telescope Exhibit Provides a Glimpse of the Universe

Robert Downes - October 9th, 2003
Not since Galileo turned his telescope towards the heavens in 1610 has any event so changed our understanding of the universe as the deployment of the Hubble Space Telescope.
And you can see for yourself with a new exhibition of space photography at the Dennos Museum Center entitled, “Heavens Above: Photographs of the Universe from the Hubble Space Telescope,“ which runs Sept. 28 – Feb. 29, 2004.
Orbiting 375 miles above the Earth, the Hubble Space Telescope is unlocking the secrets of the universe through its observations of more than 25,000 stars, nebula, planets and galaxies -- and that‘s just the beginning. With pin-point precision, powerful optics, and state-of-the-art instruments it produces spectacular views that cannot be obtained from ground-based telescopes which are hampered by the earth‘s atmosphere. As of March, 2000, it had taken more than 330,000 photos. Circling the globe every 97 minutes, it has traveled more than 1.5 billion miles over the past 13 years -- the distance from Earth to Uranus.
Designed in the ‘70s and launched in 1990 at a cost of $1.5 billion, the Hubble was placed in orbit by the space shuttle Discovery. NASA scientists were heart-broken to learn, however, that there was a spherical aberration on the telescope‘s primary mirror, which wrecked its vision. That initial failure sent political shock waves through the space agency as NASA became a target for a number of politicians.
Over the next few years, however, space shuttle astronauts installed corrective optics and gyroscopes on the Hubble in a series of dramatic missions which got the telescope working properly. Shuttle servicing missions are ongoing and planned into the future in order to install new sensing and visual technology to help scientists in their exploration of the universe.
The scope was named after American astronomer Edwin P. Hubble, who was a staff member (from 1919) at Mt. Wilson Observatory. Hubble used Mt. Wilson‘s 100-inch telescope to discover that there are large-scale galaxies beyond the Milky Way and that they are distributed almost uniformly in all directions. In what is now known as Hubble‘s Law, he was the first to offer evidence supporting the theory of the expanding universe.
The Dennos exhibit features 30 breathtaking, high-resolution color transparencies of planets, galaxies, star clusters and other deep-space phenomena. The exhibition was organized by the NASA Space Telescope Science Institute and the Midland Center for the Arts.
The Hubble exhibit kicks off a season of exceptional photography at the Dennos. Future shows will include an exhibition on the history of photography, including what it believed to be the first photograph ever created. On November 13, rock music photographer Tom Wright will host the world premiere of his exhibition, “An Assortment of Used Rock and Roll and Cultural Photography,“ which will also feature musical artifacts from the hey-day the ‘60s and ‘70s.
The Dennos Museum Center is open daily 10 a.m. to 5 p.m. and Sundays 1-5 p.m. Admission is $4 adults, $2 for children and free to museum members.
