The first images taken by the James Webb Space Telescope (JWST) have been released by NASA, following an initial reveal by US President Joe Biden.
JWST’s stunning first science image, which was unveiled by Biden on Monday, is a deep view into the universe showing thousands of galaxies, showcasing the immense power of the $10 billion telescope. NASA has now released more of the telescope’s initial observations, taken in its first few months of commissioning following its launch in December 2021.
One of those observations was a detailed study of the atmosphere of a gas giant planet 1,000 light-years from Earth called WASP-96 b. By watching the dip in light as the planet passed in front of its host star, JWST was able to probe the atmosphere of this world, a technique it will use to study many more planets in the future.
“You’re seeing bumps and wiggles that indicate the presence of water vapor in the atmosphere,” said Knicole Colón, an astrophysicist at NASA Goddard Space Flight Center and the James Webb Space Telescope deputy project scientist for exoplanet science, in a NASA event that revealed the observations.
“These are probably the most difficult observations that JWST will make,” says Don Pollacco, an astronomer at Warwick University in the UK. JWST is expected to have an unmatched ability to look for methane and other potential signatures of life in the atmospheres of planets similar in size to our own.

Also unveiled today was JWST’s view of a dying star throwing off its outer layers, a so-called planetary nebula known as the Southern Ring Nebula that sits some 2,500 light-years from Earth. The view is far more detailed than that of an image taken by the Hubble Space Telescope in 1998 and reveals for the first time the two stars known to be at the heart of the nebula.
Another image (shown at the top of this story) reveals an exquisite view of Stephan’s Quintet, a group of five galaxies about 300 million light-years from Earth. Four of these galaxies are interacting, transferring gas and dust between them. JWST’s view of the galaxies in infrared light shows how those interactions are driving the formation of stars inside the galaxies like never before. The power of JWST’s optics are so great that individual stars can even be seen inside the galaxies. “It’s remarkable,” said Mark McCaughrean, senior advisor for science and exploration at the European Space Agency. “We’re ready to turn this telescope up to 11.”

The final image on offer was a fresh look at the Carina Nebula, a region of active star formation nearly 8,000 light-years from Earth. The magnificent vista unveiled by JWST reveals hundreds of new stars never seen before, and even structures in the dust and gas of the nebula that can’t yet be explained, said Amber Straughn, an astrophysicist at NASA Goddard and deputy project scientist for the JWST.
“We’re able to see so much more detail,” thanks to JWST, says Straughn. “It really does reveal what’s going on here.”

Stitching together the grid will save lives as extreme weather worsens
The blistering heat waves that set temperature records across much of the US in recent days have strained electricity systems, threatening to knock out power in vulnerable regions of the country.
The electricity has largely stayed online so far this summer, but there have been scattered problems and close calls already.
Heavy use of energy-sucking air-conditioners is the biggest problem. But intense heat can also reduce the output of power plants, blow transformers, and force power lines to sag. Severe droughts across large parts of the country have also significantly reduced the availability of hydroelectric power, according to the North American Electric Reliability Corporation (NERC).
It’s unlikely to get better soon. A number of grid operators may struggle to meet peak summer demand, creating the risk of rolling blackouts, the NERC report notes.
The nation’s isolated and antiquated grids are in desperate need of upgrades to keep the lights, heat, and air-conditioning on in the midst of extreme weather events that climate change is making more common, severe, and dangerous. One clear way to ease many of these issues is to more tightly integrate the country’s regional grids, stitching them together with more long-range transmission lines.
If electricity generated in one area can be more easily shared across much wider regions, power can simply flow to where it’s needed at those moments when customers crank up air-conditioners en masse, or when power plants or fuel supply lines fail amid soaring temperatures, wildfires, hurricanes, or other events, says Liza Reed, a research manager focused on transmission at the Niskanen Center, a Washington, DC, think tank.
The problem is it’s proved difficult to build more long-range transmission and grid interconnections for a variety of reasons, including the permitting challenges of erecting wires through private and public lands across cities, counties, and states and the reluctance of local authorities to forfeit control or submit to greater federal oversight.
The case of Texas
The unreliability of the US grid is not a new problem. Severe heat and winter storms have repeatedly exposed the frailty of electricity systems in recent years, leaving thousands to millions of people without power as temperatures spiked or plunged.
One of the fundamental challenges is that the grids today are highly fragmented. There are three main electricity networks within the US: the Eastern Grid, the Western Grid, and the Electric Reliability Council of Texas (ERCOT). But there are numerous regional transmission organizations within those first two systems, including the California Independent System Operator, Southwest Power Pool, PJM Interconnection, New York ISO, and more.
These grids form a complex web of networks operating under different regulators, rules and market structures, and often with limited connections between them.
A variety of regional transmission organizations oversee different parts of the nation’s aging and fragmented grids, which operate under different rules and with often limited connections between them.
ERCOT is especially isolated, in part because of the desire among local politicians, citizens, and power companies to avoid added competition, the hassle of following other states’ rules, and oversight from the Federal Energy Regulatory Commission (FERC). But the state offers a case study in why that can be a serious problem amid increasingly harsh climate conditions, Reed says.
The Texas grid operator pleaded with customers several times earlier this month to cut electricity use as blistering summer temperatures created demand surges that threatened to outstrip supply and require rolling blackouts. Low wind conditions, cloud cover, and outages at fossil-fuel power plants added to the strains.
