NASA SPHEREx space telescope has captured its 1st images of cosmos: See stunning photos
NASA's newest space telescope has officially begun snapping some incredible images of the cosmos about two months after it got off the ground.
SPHEREx, which the U.S. space agency sent on a mission to unravel some of the universe's biggest mysteries, first released a debut batch of uncalibrated images in April unsuited for scientific study.
What followed was about six weeks of procedures to make sure the advanced instrument is working as it should.
Now, the telescope has commenced mapping not just a section of the sky, but all of it as part of NASA's goal of charting the positions of hundreds of millions of galaxies in three-dimension. As of May, that includes taking some 3,600 images per day.
NASA released a sampling of those images May 1, which the space agency hopes are just the tip of the iceberg. Ultimately, scientists hope SPHEREx will provide data lending new insights into the origins of the universe and whether the ingredients for life exist anywhere else in our Milky Way galaxy.
Here's a look at some of SPHEREx's first images, as well as what to know about the observatory's two-year mission.

Throughout the next 25 months, the SPHEREx observatory will orbit Earth more than 11,000 times while surveying and imaging the surrounding sky.
When SPHEREx takes pictures of the sky, the light is sent to six detectors that can capture different wavelengths of light, or exposures.
By the mission's end, NASA will weave hundreds of thousands of SPHEREx's images into digital sky maps.
Here's a look at two of the newest photos:
What is the SPHEREx mission? Telescope to study origins of universe
SPHEREx, short for Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, was developed by NASA for a mission to uncover some of the universe's greatest mysteries.
The advanced observatory, an 8½ foot-tall cone-shaped telescope with infrared capabilities, will create a 3D map of the entire celestial sky every six months.
SPHEREx will also use a technique called spectroscopy to measure the distance to 450 million galaxies in the nearby universe. Astronomers theorize that the distribution of the galaxies was influenced by a universe-expanding event that took place almost 14 billion years ago after the big bang.
During its mission, the telescope will also measure the glow of all the galaxies in the universe, which should provide new insights into how galaxies formed and evolved over cosmic time.
But the mission isn't only studying faraway galaxies. SPHEREx will also turn its attention to our Milky Way to search for hidden reservoirs of frozen water ice and other molecules, like carbon dioxide, that are essential to life as we know it.
When and where did the SPHEREx telescope launch?
The telescope got off the ground March 12 aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in Vandenberg, California.
The space observatory shared a ride with the four small satellites that make up NASA's PUNCH mission, which will study how the sun's outer atmosphere becomes solar wind.
The two missions are designed to operate in low-Earth orbit in such a way that the sun always remains in the same position relative to each spacecraft. This is essential for SPHEREx to keep its telescope shielded from the sun's light and heat, which would inhibit its observations, and for PUNCH to have a clear view in all directions around the sun, according to NASA.
How is SPHEREx different from James Webb Space Telescope, Hubble Space Telescope?
NASA believes SPHEREx could complement the famous Hubble and James Webb space telescopes, which have for years already been studying the far corners of the known universe.
Hubble and Webb specialize in zooming in on small areas in great detail, unveiling planets, stars and galaxies in high resolution. But some questions "can be answered only by looking at the big picture," according to NASA.
That's where SPHEREx comes in.
The new telescope could help fill in the gap by getting a wider view of the galaxy – identifying objects of scientific interest that telescopes like Hubble and Webb can then go study up close. The result would provide scientists with a more complete perspective of the universe, according to NASA.

SpaceX late-night rocket launch in Florida could be visible in Jacksonville: Where to watch it
A late-night rocket launch from Florida is on the horizon. SpaceX is set to launch a batch of Starlink satellites into low-Earth orbit on June 22 from Cape Canaveral. Rockets here launch from NASA's Kennedy Space Center or nearby Cape Canaveral Space Force Station. Weather permitting and depending on cloud cover, a rocket launch from Florida's Space Coast could be visible as far north as Jacksonville Beach and Daytona Beach to as far south as Vero Beach and West Palm Beach. When there's a launch window in the middle of the night or very early morning, there's an opportunity for unique photos — the rocket lights up the dark sky and the contrail after makes for a great photo. Below is more information about the SpaceX rocket launch in Florida and suggestions on where to watch them from here.

Investors should consider this growth stock… it's SpaceX's competition
Rocket Lab (NASDAQ:RKLB) is a US-listed growth stock that gives investors rare access to the commercial space sector. As a vertically integrated launch and space systems provider, Rocket Lab is often compared to SpaceX in its ambition and capabilities. But there's one crucial difference: you can actually buy shares in Rocket Lab, while SpaceX remains private. Rocket Lab delivers launch services, builds small and medium-class rockets, and manufactures spacecraft components for a range of commercial, government, and defense customers. With rapid revenue growth, an impressive order book, and expansion into new markets, Rocket Lab offers public market investors a way to participate in the booming space economy. It targets many of the same opportunities as its more famous, privately held peer. Rocket Lab and SpaceX operate in the same commercial space sector but differ significantly in scale, maturity, and valuation. Rocket Lab's market cap is currently $12.85bn, with trailing 12 months (TTM) revenue of approximately $460m. Despite strong growth — revenue nearly doubled from $240m in 2023 — Rocket Lab remains a smaller, earlier-stage player focused on small to medium launch vehicles and spacecraft manufacturing. Its valuation multiples are extremely high, with a forward price-to-sales ratio of 22.3 times, reflecting investor optimism. SpaceX, by contrast, is a far more mature private company valued at about $350bn. It's projected to generate $15.5bn in revenue in 2025. This is driven by its dominant Falcon 9 launch services and rapidly growing Starlink satellite internet business. SpaceX's valuation implies roughly a 22.5 times multiple on forward revenue. This is broadly in line with Rocket Lab. Focusing on Rocket Lab, the company is projected to deliver rapid revenue growth over the next several years, with estimates rising from $573m in 2025 to $889 in 2026, $1.2bn in 2027, and $1.69bn in 2028. This represents annual growth rates consistently above 30%, and even a jump of nearly 77% in 2030. However, the number of analysts providing forecasts declines sharply after 2027, dropping from 11–14 analysts in the near term to just two or one by 2028 and 2030. The one analyst projecting as far as 2030 sees $4bn in revenue for the year. I had the chance to buy Rocket Lab shares at $15 just two months ago. I missed out as unfortunately my attention had been diverted elsewhere. However, I found another entry point. And personally, I see this as an investment to hold for a very long period. The space industry is still in its early innings, with enormous potential as satellite launches, lunar missions, and in-orbit services become increasingly mainstream. And like any investment, there are risks. Rocket Lab remains loss-making. It's expected to turn a profit in 2026, when it will trade at 620 times earnings. And while this moderates to 140 times in 2027, it's still expensive and introduces plenty of execution risk. However, I certainly believe UK investors should consider this one. It could be a real winner going forward. The post Investors should consider this growth stock… it's SpaceX's competition appeared first on The Motley Fool UK.
