Kelly Warm Springs

Slightly Northeast of Jackson Hole, Wyoming, just past the town of Kelly, there is a small pond called Kelly Warm Springs. You’ll never see more than about seven people there at once since it is somewhat out of the way of the main roads. It’s not the biggest hot spring in the area with Yellowstone just about an hour North of it, and it’s also not the hottest one averaging only 81º Fahrenheit (27.2º Celsius) year round. The pool is perfect for summer swimming with a gorgeous backdrop of the Grand Tetons visible from the whole pool.

Studies on Longing/Seeing (2017) by Kerstin Ergenzinger (DE); using a reactive system connected to a geophone and a seismograph the installation senses the location’s seismic activity and simulates them through constant movements; a fact of the Earth’s constant movement and changing which we tend to forget and the artist connects to our longing for stability and security.

Sculptures found in ancient city of Pisidia Antiokheia

Five sculptures of gods and goddesses have been found in the sanctuary of Mēn Askaenos in the ancient city of Pisidia Antiokheia in Turkey. AA PhotoExcavations close to the ancient city, located in the southern province of Isparta’s Yalvaç district, unearthed the five intact sculptures in one of the previously unearthed prestigious chambers. AA PhotoExcavations head Professor Mehmet Özhanlı said the sculptures of the goddesses…

Comments of the Week #180: From the planets Kepler missed to the NASA photos that changed the world

“Everything is subject to revision. I have no doubt that if we continue to do science at the rate that we’ve done it over the past few hundred years, then by time the year 3,000 rolls around, we’ll look at much of our modern understanding of things the way we look at Copernicus’ or even Ptolemy’s “Universe” today: as quaint, as the beginnings of science, but full of bad ideas and assumptions that we didn’t even recognize. But we may look at it only as we look at Newton’s: as incredibly good, and fundamentally flawed and limited in a few ways, but super successful for its time and what it did nonetheless.

We are always learning and growing.”

There is so much that’s out there in the Universe that we have not seen; that we cannot be certain of with 100% evidence. But thanks to what we know, and the theories we can lay atop the evidence we have, we can make some incredibly powerful predictions, and that’s my favorite part of any scientific theory.

Also, my new book, Treknology, is out today! #Celebrate

Come enjoy all the spectacular bonus science you’ve come to expect, and check out this edition of our Comments of the Week!

Magnetosphere of Jupiter

The magnetosphere of Jupiter is the cavity created in the solar wind by the planet’s magnetic field. Extending up to seven million kilometers in the Sun’s direction and almost to the orbit of Saturn in the opposite direction, Jupiter’s magnetosphere is the largest and most powerful of any planetary magnetosphere in the Solar System, and by volume the largest known continuous structure in the Solar System after the heliosphere. Wider and flatter than the Earth’s magnetosphere, Jupiter’s is stronger by an order of magnitude, while its magnetic moment is roughly 18,000 times larger. The existence of Jupiter’s magnetic field was first inferred from observations of radio emissions at the end of the 1950s and was directly observed by the Pioneer 10 spacecraft in 1973.

The Remarkable Jet of the Quasar 4C+19.44

A Chandra X-ray image of the quasar 3C19.44. The overlayed contours show the radio emission (the dimension 100kpc corresponds to 329,000 light-years; the extremely bright core produces a line of bright pixels as an artifact). NASA/Chandra VLA and Harris et al.

Quasars are galaxies with massive black holes at their cores. So much energy is being radiated from near the nucleus of a quasar that it is much brighter than the rest of the entire galaxy. Much of that radiation is at radio wavelengths, produced by electrons ejected from the core at speeds very close to that of light, often in narrow, bipolar jets that are hundreds of thousands of light-years long. The fast-moving charged particles can also scatter photons of light, kicking them up in energy into the X-ray range. Even after more than two decades of study, however, there is still no clear conclusion as to the physical mechanism actually responsible for the X-ray emission. In more powerful quasars, it does appear that this scattering process dominates. In lower power jets, however, the emission characteristics suggest that the X-ray emission is dominated by magnetic field effects, not scattering.

The lead author of a new paper on the remarkable jet in the quasar 4C+19.44 is CfA astronomer Dan Harris, who very sadly passed away in December, 2015, after a long and productive career. His CfA teammates on this project, Dan Schwartz with Nicholas Lee and Aneta Siemiginowska, worked to finish the research together with an international team of colleagues. The scientists undertook a detailed, high spatial resolution study of the straight, three hundred thousand light-year long jet in this quasar using multiwavelength data from the Chandra (X-ray), Spitzer (infrared), and Hubble (optical) space observatories as well as from the Very Large Array (radio).

The combination of multiwavelength observations with high spatial resolution enabled the team to measure the characteristics of the emission systematically in ten distinct knots along the jets. They find that both the magnetic field strength and the particle velocities are (remarkably) quite constant all along the length of this jet, at least when presuming the scattering process dominates. But the scientists are not able to exclude magnetic effects as producing some of the X-ray emission. They do conclude, however, that for the magnetic process to be active, any electrons contributing to it must belong to a separate population that is distinct from the electrons that dominate the scattering.

Hi, DC! Divine Felines: Cats of Ancient Egypt is now on view at the Smithsonian’s Freer and Sackler Galleries until January 15. Ranging from domesticated cats to mythic symbols of divinity, the exhibition highlights the important role of cats in ancient Egyptian imagery. If you have a friend in the area who you think will enjoy the show, share this with them and tell them to check it out!
