WASHINGTON, Jan 29 (Reuters) — A batch of newly released images captured by the James Webb Space Telescope show in remarkable detail 19 spiral galaxies residing relatively near our Milky Way, offering new clues on star formation as well as galactic structure and evolution.

The images were made public on Monday by a team of scientists involved in a project called Physics at High Angular resolution in Nearby GalaxieS (PHANGS) that operates across several major astronomical observatories.

The closest of the 19 galaxies is called NGC5068, about 15 million light years from Earth, and the most distant of them is NGC1365, about 60 million light years from Earth.

A light year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

The James Webb Space Telescope (JWST) was launched in 2021 and began collecting data in 2022, reshaping the understanding of the early universe while taking wondrous pictures of the cosmos.

The orbiting observatory looks at the universe mainly in the infrared.

The Hubble Space Telescope, launched in 1990 and still operational, has examined it primarily at optical and ultraviolet wavelengths.

Spiral galaxies, resembling enormous pinwheels, are a common galaxy type. Our Milky Way is one.

The new observations came from Webb's Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI).

They show roughly 100,000 star clusters and millions or perhaps billions of individual stars.

"These data are important as they give us a new view on the earliest phase of star formation," said University of Oxford astronomer Thomas Williams, who led the team's data processing on the images.

"Stars are born deep within dusty clouds that completely block out the light at visible wavelengths - what the Hubble Space Telescope is sensitive to - but these clouds light up at the JWST wavelengths.

We don't know a lot about this phase, not even really how long it lasts, and so these data will be vital for understanding how stars in galaxies start their lives," Williams added.

About half of spiral galaxies have a straight structure, called a bar, coming out from the galactic center to which the spiral arms are attached.

"The commonly held thought is that galaxies form from the inside-out, and so get bigger and bigger over their lifetimes.

The spiral arms act to sweep up the gas that will form into stars, and the bars act to funnel that same gas in towards the central black hole of the galaxy," Williams said.

The images let scientists for the first time resolve the structure of the clouds of dust and gas from which stars and planets form at a high level of detail in galaxies beyond the Large Magellanic Cloud and Small Magellanic Cloud, two galaxies considered galactic satellites of the sprawling Milky Way.

"The images are not only aesthetically stunning, they also tell a story about the cycle of star formation and feedback, which is the energy and momentum released by young stars into the space between stars," said astronomer Janice Lee of the Space Telescope Science Institute in Baltimore, principal investigator for the new data.

"It actually looks like there was explosive activity and clearing of the dust and gas on both cluster and kiloparsec (roughly 3,000 light years) scales.

The dynamic process of the overall star formation cycle becomes obvious and qualitatively accessible, even for the public, which makes the images compelling on many different levels," Lee added.

Webb's observations build on Hubble's.

"Using Hubble, we would see the starlight from galaxies, but some of the light was blocked by the dust of galaxies," University of Alberta astronomer Erik Rosolowsky said.

"This limitation made it hard to understand parts of how a galaxy operates as a system. With Webb's view in the infrared, we can see through this dust to see stars behind and within the enshrouding dust."

Perspective view of Mars’s Tharsis volcanoes by European Space Agency Via Flickr: This oblique perspective view shows a slice of Mars imaged to mark a milestone for ESA’s Mars Express: its 25 000th orbit around the Red Planet. It was generated from a digital terrain model and the nadir (downward-pointing) and colour channels of Mars Express’s High Resolution Stereo Camera. The vertical scale is exaggerated by a factor of approximately three, making the volcanoes look three times higher than they are in real life. Three of Mars’s famously colossal volcanoes are shown here: from left to right, Arsia, Pavonis and Ascraeus Mons. The mound of Mars’s largest volcano, Olympus Mons, can be spied further away at the top of the frame, while the fractured terrain of Noctis Labyrinthus, Mars’s ‘labyrinth of night’, can be seen in the foreground.

Microscope system sharpens scientists’ view of neural circuit connections

New Post has been published on https://thedigitalinsider.com/microscope-system-sharpens-scientists-view-of-neural-circuit-connections/

Microscope system sharpens scientists’ view of neural circuit connections

The brain’s ability to learn comes from “plasticity,” in which neurons constantly edit and remodel the tiny connections called synapses that they make with other neurons to form circuits. To study plasticity, neuroscientists seek to track it at high resolution across whole cells, but plasticity doesn’t wait for slow microscopes to keep pace, and brain tissue is notorious for scattering light and making images fuzzy. In an open access paper in Scientific Reports, a collaboration of MIT engineers and neuroscientists describes a new microscopy system designed for fast, clear, and frequent imaging of the living brain.

The system, called “multiline orthogonal scanning temporal focusing” (mosTF), works by scanning brain tissue with lines of light in perpendicular directions. As with other live brain imaging systems that rely on “two-photon microscopy,” this scanning light “excites” photon emission from brain cells that have been engineered to fluoresce when stimulated. The new system proved in the team’s tests to be eight times faster than a two-photon scope that goes point by point, and proved to have a four-fold better signal-to-background ratio (a measure of the resulting image clarity) than a two-photon system that just scans in one direction.

“Tracking rapid changes in circuit structure in the context of the living brain remains a challenge,” says co-author Elly Nedivi, the William R. (1964) and Linda R. Young Professor of Neuroscience in The Picower Institute for Learning and Memory and MIT’s departments of Biology and Brain and Cognitive Sciences. “While two-photon microscopy is the only method that allows high-resolution visualization of synapses deep in scattering tissue, such as the brain, the required point-by-point scanning is mechanically slow. The mosTF system significantly reduces scan time without sacrificing resolution.”

Scanning a whole line of a sample is inherently faster than just scanning one point at a time, but it kicks up a lot of scattering. To manage that scattering, some scope systems just discard scattered photons as noise, but then they are lost, says lead author Yi Xue SM ’15, PhD ’19, an assistant professor at the University of California at Davis and a former graduate student in the lab of corresponding author Peter T.C. So, professor of mechanical engineering and biological engineering at MIT. Newer single-line and the mosTF systems produce a stronger signal (thereby resolving smaller and fainter features of stimulated neurons) by algorithmically reassigning scattered photons back to their origin. In a two-dimensional image, that process is better accomplished by using the information produced by a two-dimensional, perpendicular-direction system such as mosTF, than by a one-dimensional, single-direction system, Xue says.

“Our excitation light is a line, rather than a point — more like a light tube than a light bulb — but the reconstruction process can only reassign photons to the excitation line and cannot handle scattering within the line,” Xue explains. “Therefore, scattering correction is only performed along one dimension for a 2D image. To correct scattering in both dimensions, we need to scan the sample and correct scattering along the other dimension as well, resulting in an orthogonal scanning strategy.”

In the study the team tested their system head-to-head against a point-by-point scope (a two-photon laser scanning microscope — TPLSM) and a line-scanning temporal focusing microscope (lineTF). They imaged fluorescent beads through water and through a lipid-infused solution that better simulates the kind of scattering that arises in biological tissue. In the lipid solution, mosTF produced images with a 36-times better signal-to-background ratio than lineTF.

For a more definitive proof, Xue worked with Josiah Boivin in the Nedivi lab to image neurons in the brain of a live, anesthetized mouse, using mosTF. Even in this much more complex environment, where the pulsations of blood vessels and the movement of breathing provide additional confounds, the mosTF scope still achieved a four-fold better signal-to-background ratio. Importantly, it was able to reveal the features where many synapses dwell: the spines that protrude along the vine-like processes, or dendrites, that grow out of the neuron cell body. Monitoring plasticity requires being able to watch those spines grow, shrink, come, and go across the entire cell, Nedivi says.

“Our continued collaboration with the So lab and their expertise with microscope development has enabled in vivo studies that are unapproachable using conventional, out-of-the-box two-photon microscopes,” she adds.

So says he is already planning further improvements to the technology.

“We’re continuing to work toward the goal of developing even more efficient microscopes to look at plasticity even more efficiently,” he says. “The speed of mosTF is still limited by needing to use high-sensitivity, low-noise cameras that are often slow. We are now working on a next-generation system with new type of detectors such as hybrid photomultiplier or avalanche photodiode arrays that are both sensitive and fast.”

In addition to Xue, So, Boivin, and Nedivi, the paper’s other authors are Dushan Wadduwage and Jong Kang Park.
