Hubble comes face-to-face with spiral's arms

by Claire Andreoli
May 12, 2025

The spiral galaxy NGC 3596 is on display in a NASA/ESA Hubble
Space Telescope image that incorporates six different wavelengths
of light. NGC 3596 is situated 90 million light-years from Earth
in the constellation Leo, the Lion. British astronomer Sir
William Herschel first documented the galaxy in 1784.

NGC 3596 appears almost perfectly face-on when viewed from Earth,
showcasing the galaxy's neatly wound spiral arms. These bright
arms hold concentrations of stars, gas, and dust that mark the
area where star formation is most active, illustrated by the
brilliant pink star-forming regions and young blue stars tracing
NGC 3596's arms.

What causes these spiral arms to form? It's a surprisingly
difficult question to answer, partly because spiral galaxies are
so diverse. Some have clear spiral arms, while others have
patchy, feathery arms. Some have prominent bars across their
centers, while others have compact, circular nuclei. Some have
close neighbors, while others are isolated.

Early ideas about how spiral arms formed stumped astronomers with
the "winding problem." If a galaxy's spiral arms are coherent
structures, its arms would wind tighter and tighter as the galaxy
spins, until the arms are no longer visible.

Now, researchers believe that spiral arms represent a pattern of
high-density and low-density areas rather than a physical
structure. As stars, gas, and dust orbit within a galaxy's disk,
they pass in and out of the spiral arms. Much like cars moving
through a traffic jam, these materials slow down and bunch up as
they enter a spiral arm, before emerging and continuing their
journey through the galaxy.

From Deutsche Welle:

Can public transport ever replace cars?

Jonas Mayer
May 13, 2025

Better train and bus services could mean cleaner air and less
congestion. But are car owners ever likely to switch?

Scattered among the ever-moving traffic of Indonesia's capital,
Jakarta, are a couple of thousand blue and white minibuses. They
travel to every corner of the city, carrying an endless stream of
people who hop on and off without having to worry about the
hassle of parking.

The network is a vital part of this 11-million-strong megacity's
answer to a big problem. Too much motorized traffic.

Jakarta is not alone. Globally, air pollution and road accidents
caused by cars, vans and motorbikes kill around two million
people each year, and combustion engine vehicles account for
around 10% of the global carbon emissions causing climate change.

For decades, the response to a growth in traffic has been to
build more lanes, flyovers and parking. But this only attracts
more cars and greater potential for congestion.

Now in a bid to for safer, decongested roads and cleaner air,
some cities and countries are trying to get their citizens to
ditch cars in favor of public transport. Their approaches are as
varied as the results.

How enticing is free public transport?

Some cities, such as the Estonian capital Tallinn, have opted for
a seemingly simple solution. In a 2012 referendum, residents of
the almost half a million-strong city voted to make trains, trams
and buses free for locals. Since 2013, the cost of public
transport has fallen to the city government, to the tune of
around €40 ($45) per person annually — with mixed results,
according to Merlin Rehema, a sustainable city researcher with
the nonprofit research group, Stockholm Environment Institute.

"Ridership has fallen dramatically, from 42% to now like 30%,"
Rehema said, adding that car use has gone up by about 5%. "People
who were using public transport anyways, are now using it more
often. And to some extent, short walks and bicycle trips that
were taken before also became bus trips."

Other places — such as Luxembourg, the island of Malta and the US
city of Kansas City — that have also made their public
transportation fare-free, report similar outcomes. Researchers
attribute this in part to Covid-era restrictions, but that is not
all that's at play.

For the love of the automobile

Pete Dyson, a behavioral scientist at the UK's Bath University,
says decisions around how people choose to travel also come down
to psychology.

"When people look at the psychological aspects of car ownership,
they typically look at areas of status and of pride," Dyson said,
adding that cars also meet a fundamental human need for safety
and comfort in a way that delayed and crowded buses do not.

He adds that this need can be addressed by giving buses priority
over cars to make journeys smoother, punctual, and more reliable.
And by making public transport "a safer environment, a more
comfortable environment."

Ensuring other benefits like "access to a seat or a table, or the
ability to do useful or meaningful things while travelling,"
would help too.

Riding the bus with TransJakarta

That's the way things are moving in Jakarta. Buses are
air-conditioned, have a separate seating area for women, and
staff are on hand for any assistance and information required.
Buses painted pink are women-only. Each trip costs the equivalent
of €0.20.

Around 10% of trips in the city are currently made by bus and
train, a number the government wants to increase that number
sixfold by 2030. But car and motorcycle traffic are growing.

"The major challenge here, or the major homework here, is to push
people to use public transport," said Gonggomtua Sitanggang, the
Southeast Asia Director of the non-profit Institute for
Transportation and Development Policy.

So far, Jakarta has established what is known as a Bus Rapid
Transit (BRT) system, which repurposed existing lanes to create
14 bus-only corridors. The TransJarkarta network, as it is
called, covers 250 kilometers or 155 miles and is connected to
the 2,200 blue and white minibuses that can be caught within 500
meters of most places across the city.

"And these minibuses are free of charge to incentivize people to
use public transport," said Sitanggang, adding that this kind of
first and last-mile connectivity is important to create access to
public transport.

Discouraging car ownership

Some cities are taking a different approach and are trying to
make driving less appealing, such as through levies. From this
year, car owners in Estonia will have to pay both an initial
registration fee and an annual vehicle tax.

Meanwhile, London established a congestion charge zone that saw
car traffic fall and bus and tube usage go up.

But Merlin Rehema says there are other ways to disincentivize
driving, such as "really redesigning your cities in order to
favor public transport use."

This is what Paris has been doing by removing tens of thousands
of parking lots, closing entire roads to cars and tripling
parking fees for big and polluting SUVs.

Jakarta is also starting to redesign infrastructure in the
central zone of Dukuh Atas, which has tens of thousands of
parking spaces but also sits at a major public transport hub with
bus and rail connections.

"We start by improving the connectivity, the pedestrian and
cycling facilities, and then we develop a strategy of how to
reduce the parking space within the area," said Sitanggang.

Even cities that cannot quickly transform infrastructure can take
action, Dyson said. "Some quick fixes to an existing network
would be improving the quality of information about routes and
wayfinding and making tickets and fares simpler."

As the days wind down towards opening day of Hamvention in Xenia, Ohio, organizers report brisk ticket sales and the hope to match or exceed last year's attendance of more than 35,000 guests over the three days. A team of 700-plus
volunteers will be there starting on May 16th to make everyone welcome. This year's theme is "Radio Independence" and for three days it will pervade the four meeting halls where the forums are taking place.

Tickets can be purchased at the box office outside the main entrance gate. For additional details visit www.hamvention.org

The ARRL is also encouraging visitors to download the Hamvention app which includes the full program and affiliated events.

Hamvention is 16 - 18 May 2025
