The Royal Astronomical Society of Canada’s observatory in Hamilton, Ontario was vandalized earlier this month, with at least $100,000 in damage to equipment and facilities.

Security video shows two people using a truck to repeatedly ram into two buildings – the observatory and a meeting center — knocking down exterior walls on both buildings and damaging telescopes and other equipment inside. Nothing was stolen, but damaged for no apparent reason.

“It appears to be a failed robbery turned utter vandalism,” said the group’s president Andy Blanchard. “It looked like they wanted to destroy everything.”

Blanchard told Universe Today that another member of the group discovered the damage on July 4, 2023 when he went out to the center to do some maintenance. He first saw that a heavy-duty entrance gate had been ripped out of the ground, but that was only the start.

“It was shocking and upsetting and it took us about 3-4 hours to manage to get into the clubhouse building to access to security video,” Blanchard said “On that video we saw they backed their truck into the observatory wall three times to knock it down, and they spent 5 minutes in the building, doing further damage to our equipment, such as throwing eyepieces to the floor. Then they used their truck to knock down the walls on our meeting and warming center, but the wall collapsed in a way that they couldn’t enter the building.”

The police say the two perpetrators are known and are being sought in connection with this and several other break-ins and acts of vandalism in the area in southern Ontario.

The Hamilton Centre of the RASC is one of 28 non-profit centers across Canada, powered by over 140 astronomy enthusiast members. The Hamilton group was originally founded 1901, and is one of the longest standing amateur astronomy organizations in Canada.

When the wall on the observatory was knocked down, it crushed a CGE Pro mount from Celestron, hurling the mounted telescope, worth at least $11,000 USD, across the room. In total, the astronomical equipment damaged is valued at more than $40,000 USD.

Blanchard said that’s a substantial amount for a group of volunteers that are doing a public service by sharing the wonders of the night sky with their community.

“It was basically several decades worth of collection and work,” Blanchard said. “The biggest problem is that when the wall came down, the lime dust from the concrete walls settled on all the astronomical surfaces, and lime is very caustic to the expensive coatings on the eyepieces and optics. All have to be sent away for repair.”

The group has started a GoFundMe page, and club member Jeff Parsons said their story seems to have struck a cord, “evidenced by the growing outpouring of support and generosity from not just the local community but the broad astronomy community.”

Blanchard said they’ve been overjoyed with the support they’ve received, with both cash donations, as well as of offers for help with reconstruction of their buildings.

“It’s a wonderful feeling to get such support from around the world,” Blanchard said. “Many times, you don’t realize you are part of a community until that community comes together for support. We are very proud of our community and all the people who are stepping up and saying they want to help.”

But the group has also received offers of substantial donations, such as an observatory and other astronomical equipment. Additionally, a recognized member of the Canadian astronomy community offered to donate a

By Michael Lanza

Chances are that, by now, you’ve heard of Idaho’s Sawtooths—having typed that name into a search box may be the reason you’ve landed on this story. Maybe you’ve been intrigued at what you’ve heard or images you’ve seen from Idaho’s best-known mountain range. Perhaps you’ve even been there and the experience has only amplified your curiosity to see more of this range.

As someone who’s had the good fortune of having backpacked all over the country and in many other countries over the past three-plus decades, including the 10 years I spent as a field editor for Backpacker magazine and even longer running this blog, I rank the Sawtooths among the 10 best backpacking trips in America.

I’ve wandered around the Sawtooths at least a couple dozen times over more than two decades, including numerous backpacking trips, dayhikes, peak scrambles, rock climbing, and backcountry skiing. While there remain peaks on my list to climb, a few trails to hike, and many lakes to leap into (or just sit beside), the Sawtooths have become my backyard mountains. I feel at home there.

This story presents the five reasons I think every backpacker should take a multi-day hike through the Sawtooths—spotlighting the characteristics of a trip there that make this place unique. I believe this argument may persuade you to go (if, somehow, the photos don’t do it).

See my e-book “The Best Backpacking Trip in Idaho’s Sawtooth Mountains” to learn all you need to know to plan and pull off a five-day, 36-mile Sawtooths hike through the core of the Sawtooths, and my Custom Trip Planning page to learn how I can help you plan every detail of a multi-day hike there.

The Venerable Hubble Space Telescope Keeps Delivering

NGC 4753 dust lanes zoom 1024x469 1

The world was much different in 1990 when NASA astronauts removed the Hubble Space Telescope from Space Shuttle Discovery’s cargo bay and placed it into orbit. The Cold War was ending, there were only 5.3 billion humans, and the World Wide Web had just come online.

Now, the old Soviet Union is gone, replaced by a smaller but no less militaristic Russia. The human population has ballooned to 8.1 billion. The internet is a fixture in daily life. We also have a new, more powerful space telescope, the JWST.

But the Hubble keeps delivering, as this latest image shows.

The lenticular galaxy NGC 4753 is about 60 million light-years away. Lenticular galaxies are midway between elliptical and spiral galaxies. They have large-scale disks but only poorly defined spiral arms. NGC 4753 sees very little star formation because like other lenticulars, it’s used up most of its gas. The fact that they contain mostly older stars makes them similar to elliptical galaxies.

Among lenticulars, NGC 4753 is known for the dust lanes surrounding its nucleus. Astronomers think that spirals evolve into lenticulars in dense environments because they interact with other galaxies and with the intergalactic medium. However, NGC 4753 is in a low-density environment. Its environment and complex structure make it a target for astronomers to test their theories of galaxy formation and evolution.

This Hubble image is the sharpest ever taken of NGC 4753, revealing its intriguing complexity and highlighting the space telescope’s impressive resolving power.

Astronomers think that NGC 4753 is the result of a merger with a dwarf galaxy over one billion years ago. The dwarf galaxy was gas-rich, and NGC 4753's distinct dust rings probably accreted from the merger. NGC 4753's powerful gravity then shaped the gas into the complex shapes we see in this image.

NGC 4763’s unique structure results from a merger with a dwarf galaxy about 1.3 billion years ago. The video below from NOIRlab explains what happened.

NGC 4753 also hosts two known Type 1a supernovae, which are important because they help astronomers study the expansion of the Universe. They serve as standard candles, an important rung in the cosmic distance ladder.

Galaxies like NGC 4753 may not be rare, but the viewing angle plays a key role in identifying them. Our edge-on view of the galaxy makes its lenticular form clear. We could be seeing others like it from different angles that obscure its nature.

This is a model of NGC 4753, as seen from various viewing orientations. From left to right and top to bottom, the angle of the line of sight to the galaxy's equatorial plane ranges from 10° to 90° in steps of 10°. Although galaxies similar to NGC 4753 may not be rare, only certain viewing orientations allow for easy identification of a highly twisted disk.

Juno Reveals Secrets About Europa’s Icy Surface

galileo feature 1024x576 1

Europa has always held a fascination to me. I think it’s the concept of a world with a sub-surface ocean and the possibility of life that has inspired me and many others. In September 2022, NASAs Juno spacecraft made a flyby, coming within 355 kilometres of the surface. Since the encounter, scientists have been exploring the images and have identified regions where brine may have bubbled to the surface. Other images revealed possible, previously unidentified steep-walled depressions up to 50km wide, this could be caused by a free-floating ocean! 

Juno was launched to Jupiter on 5 August 2011. It took off from the Cape Canaveral site on board an Atlas V rocket and travelled around 3 billion kilometres. It arrived at Jupiter on 4 July 2016 and in September 2022 made its closest flyby of Europa. The frozen world is the second of the four Galilean satellites that were discovered by Galileo over 400 years ago. Visible in small telescopes, the true nature of the moon is only detectable by visiting craft like Juno.

During its close fly-by, one of the onboard cameras known as Juno-Cam took the highest resolution images of the moon since Galileo took a flyby in 2000. The images supported the long held theory that the icy crusts at the north and south poles are not where they used to be. Another instrument on board, known as the Stellar Reference Unit (SRU), revealed possible activity resembling plumes where brine may have bubbled to the surface.

The ground track over Europa that was followed by Juno enabled imaging around the equatorial regions. The images revealed the usual, expected blocks of ice, walls, ridges and scarps but also found something else. Steep walled depressions that measured 20 to 50 kilometres across were also seen and they resembled large ovoid pits.

The observations of the meanderings of the north/south polar ice and the varied surface features all point towards an outer icy shell that is free-floating upon the sub surface ocean. This can only happen if the outer shell is not connected to the rocky interior. When this happens, there are high levels of stress on the ice which then causes the fracture pattern witnessed. The images represent the first time such patterns have been seen in the southern hemisphere, the first evidence of true polar wandering.

The images from the SRU surprisingly provided the best quality images. It was originally designed to detect faint light from stars for navigation. Instead, the team used it to capture images when Europa was illuminated by the gentle glow of sunlight reflected from Jupiter. It was quite a novel approach and allowed complex features to become far more pronounced than before. Intricate networks of ridges criss-crossing the surface were identified along with dark stains from water plumes. One feature in particular stood out, nicknamed ‘the Platypus’, it was a 37 kilometre by 67 kilometre region shaped somewhat like a platypus.
