Try these stargazing apps to spot constellations and more.
These astronomical maps will help you spot planets, stars and constellations in the night sky.
Stargazing with a friend or partner is a relaxing nighttime activity. But if you’re wanting to relax under dark skies and look at the stars, how will you know where to look? Or what you’re seeing? If you want to check out the celestial bodies and star clusters visible in a clear night sky, you should consider downloading a stargazing app. The best stargazing apps can give you a better map of the sky and more details about what you’re seeing.
My husband and I are far enough out in the country to see stars, but we haven’t completely escaped the city’s light pollution. Every so often before we turn in for the night, we’ll step out onto the back porch if the sky is clear, and look up. We’ve seen a shockingly bright Venus, the ISS streak by and a few shooting stars — thanks in part to help from some astronomy apps. If you want to take a look at some of the best stargazing app options, read on. These apps should help you spot planets, stars and constellations — and some of them have a free version.

Google Sky lets you explore the reaches of space through the “eyes” of the Hubble Space Telescope, the Sloan Digital Sky Survey and the Digitized Sky Survey. You can explore the wealth of information available free on mobile or desktop.
Click through the tray at the bottom of the screen to learn more about the solar system, constellations, galaxies and nebulae, views of the universe in X-ray, ultraviolet and infrared. You can also use sliding bars to see drawings of the sky by Giovanni Maria Cassini.
Plus, find where the planets are in the sky at a given time by typing the name of a planet in the search box.
The SkySafari astronomy app, which starts at $2 on iOS and free on Android, lets you hold your phone to the sky to identify planets, constellations, stars and satellites. You can also use the app to see what the sky might’ve looked like thousands of years ago, or what it will look like in the future.
Simulate past meteor showers, approaching comets and celestial events, like eclipses. SkySafari also has a constellation illustration overlay feature in case you can’t quite visualize the lion or bear that everyone else claims to see. The app also offers history, mythology and science information to accompany the images.
If you’re not sure where to get started, you can tap Tonight’s Best in the app to check out which object in the sky you could get the best look at.
The Star Tracker app works on iOS (lite) and Android to show you 88 constellations, over 8,000 and deep-sky objects, and the sun, moon and planets, all in real time. The app uses a 3D compass in AR mode that indicates the position of objects you’ve searched for. Think of it as a mobile planetarium.
To enhance constellations, Star Tracker has a graphics feature for the 12 zodiac signs and six famous deep-sky objects.
The app is free, but there’s a full version with more features for $3 and a no ads version for $1. In addition, Star Tracker Pro offers a Time Machine feature and night mode.
The International Space Station (ISS) app, available free on iOS and Android, doesn’t technically show you stars, but you can check out planets and the ISS itself. The app tracks where the in-space laboratory is currently located above the world at any given time.
Once you plug in your location — the only permission the app asks for — it can tell you how often you can expect to see the ISS in the sky. For example, residents of Louisville, Kentucky will typically be able to see the ISS between about 7:57 p.m. and 9:37 p.m. each night for about 30 seconds to a minute and a half. It’s a fleeting window — the ISS is traveling at about 17,100 miles per hour.
The app also keeps track of how long until the ISS will pass over your location again, and how long it’ll be visible. On average, it looks like the ISS is visible in a given area one to two times per day over the course of a week.
The Skyview app is $3 on iOS and $2 on Android, but both platforms have a free lite version. To use Skyview, just point your device at the sky and you can get started identifying galaxies, stars, constellations, planets — even the International Space Station. The app has night mode and an AR feature, so you can use it comfortably any time.
The app’s Sky Path’s feature lets you track objects in space to see exact locations at any date and time. In addition, Skyview has a time travel option to observe what the sky looked like in the past and might look like in the future.
No at-home space adventure is complete without the free official NASA app, which you can download for iOS or Android. Although technically you can’t use the app for stargazing in the same vein as some of the others on this list, you can still get up close and personal with space.
Check out a photo library with thousands of images constantly being updated and watch live NASA TV. In addition, the app has on-demand videos from around the agency and live streaming from the High-Definition Earth Viewing experiment on the ISS.
The app also keeps you in the know about NASA missions, launch information, upcoming sightings, news and tweets from the agency.
Star Walk 2, $3 for iOS and free for Android with in-app purchases, uses your phone’s sensors and GPS to show you a map of the night sky in real time, pinpointing the location of stars, planets, constellations, comets, the ISS and satellites.
Like SkySafari, you can tap Visible Tonight if you’re not sure where to start. The feature will tell you all upcoming astronomical events and celestial objects visible for your location. The What’s New section will also keep you posted on upcoming events. You can also view the astronomy calendar or tap the clock-face icon to select any date and time and watch the sky of different periods.

China indicates rare earths will keep flowing to EU, regardless of U.S. trade deal expiration
European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing last week.
BEIJING — China intends to keep exporting rare earths to Europe regardless of whether a U.S. trade deal with Beijing gets extended past January.
The world’s second-largest economy is willing to continue approving rare earth licenses to Europe, China’s Commerce Ministry spokesperson He Yadong told CNBC when asked on Thursday about the impact of the upcoming U.S. deadline.
Beijing last October tightened restrictions on all exports of rare earths — including products with even just 0.1% of China-sourced rare earths. The move followed a new U.S. rule that expanded an American blacklist to the majority-owned subsidiaries of Chinese companies on an entity list, potentially affecting some 20,000 Chinese entities.
However, both the U.S. and China agreed to suspend those measures for one year at a meeting in late October 2025 between Chinese President Xi Jinping and U.S. President Donald Trump. Ahead of the leaders’ latest summit last month, U.S. Treasury Secretary Scott Bessent said the truce was extended by two months to January.
Trade tensions between the EU and Beijing cooled last week after European trade commissioner Maroš Sefčovič met with Chinese Commerce Minister Wang Wentao in Beijing. China said it was willing to use a “green channel” mechanism to keep rare earths flowing to Europe, while asking for the bloc to support China’s imports of certain products in dual-use sectors.
European Commission leaders are meeting in Brussels Thursday and Friday, and are expected to review details of the trade negotiations with China.

Analysis: Why a $2 trillion deficit and 5% Treasury yields are becoming America’s biggest economic challenge
Treasury yields above 5% are raising borrowing costs for households and the federal government, highlighting the challenge of financing $2 trillion deficits.
Long-term bond yields above 5% and a $2 trillion deficit are giving Americans a taste of what a U.S. debt crisis would be like. A true emergency would hurt much more, and isn’t baked in. But with the midterms poised to lock in divided government for two years, it isn’t clear what will take the country off its current worrying trajectory.
Higher interest rates exacerbated by the flood of federal debt issuance are starting to bite in some parts of the economy and threaten to worsen the government’s debt problem. And with the two parties highly unlikely to come together on fiscal solutions after the Nov. 3 midterms, any fixes are years off in the future.
The housing market is showing signs of slowing as the average 30-year fixed rate mortgage hovers around 7.5%. Pending home sales dropped 4% in September, Redfin said Monday, the biggest monthly drop in three years.
Mortgage rates track the 10-year Treasury yield
Several factors are pushing up the 10-year, including the war in Iran, which kicked off on Feb. 28 and precipitated the rise in long-term yields. Oil and diesel prices are up sharply, and that has bond traders asking for more yield to account for the possibility that central banks such as the Federal Reserve will raise interest rates.
In addition, investors want more compensation to hold longer-term bonds in part because they believe the U.S. government will continue to flood the market with them. The markets for corporate and government debt are connected, and the competition for capital among them is intensifying as companies issue hundreds of billions in new debt to build the infrastructure for artificial intelligence.
Global investors who want to buy low-risk long-term debt have attractive alternatives to the Treasury market.
If the U.S. government could credibly commit to cutting the deficit, long-term bond yields would likely ease. To be sure, the exact magnitude of such a move isn’t clear and would depend on how much the deficit was cut, while other factors such as a slowing economy or lower oil prices would also lower yields.
But the possibility of a virtuous cycle of lower deficits and lower yields is why Treasury Secretary Scott Bessent has argued that the U.S. ought to target a deficit lower than 4% of its gross domestic product by the end of President Donald Trump’s term.
There is almost no way the U.S. will hit that target. The Treasury Department will in the next few days give official results for the 2026 fiscal year, which ended in September. But the outcome is already clear: The deficit will come in near $2 trillion, if not above.
That is likely to put the deficit in the range of 6.0-6.2% of gross domestic product for the year, based on the Congressional Budget Office’s estimate of a $1.993 trillion deficit and a projection of third quarter GDP.
Higher rates make debt reduction tougher. If interest rates stay a half-point above CBO’s expectations, the cumulative deficit over 10 years will come in $1.9 trillion higher, the agency estimates. If rates overshoot by 1.5 points, that adds $6 trillion in deficits.
CBO expects the 10-year Treasury to average 4.3% over that period, compared to 5.3% today. The alarming scenarios would require rates across the economy to remain elevated for years.
“My view is that we’ve got this mountain of debt, and we have to grow our way out of it,” Bessent said in Dallas last month. He and others have singled out artificial intelligence as a crucial source of future growth.
AI could help but can’t fix the problem entirely. It would take a decade of 7.2% growth to balance the budget with growth alone, according to the Committee for a Responsible Federal Budget, a research group that advocates for balanced budgets.
GDP growth was recently revised up for the second quarter from 1.5% to 2.2% at an annualized rate. The acceleration that quickly would get us to 7.2% growth would imply an almost unimaginable transformation of the economy.
Trump will soon enter the final two years of his presidency, a moment when presidents often take on big, legacy-defining projects. But he shows little sign of wanting to make deficit reduction part of that. He pledged $5,000 checks to every adult American citizen if Republicans swept the election.
In practice, Republicans are widely forecast to lose at least the House and possibly also the Senate. Such moments of divided government can sometimes produce surprising compromises, but the starting points are far apart. Rep. Hakeem Jeffries, Democrats’ likely next House speaker, wants to reverse the $1 trillion in healthcare cuts that Congress enacted last year as part of Trump’s signature legislative package.
And that’s leaving aside the deep animosity between the parties.
The overall U.S. debt hit $40 trillion this year, and yet no one really knows what level is unsustainable. A full-on debt crisis likely remains much farther out in the future. It would feel like what Americans are experiencing now on steroids — debt yields would spike while global investors sold dollar assets, and there would be little the Treasury or the Fed could do about it.
For now, though higher yields are also attracting investors to U.S. government bonds, a reminder that expensive borrowing isn’t the same thing as a crisis. But the bottom line is that economics alone can’t solve the problem. If Americans want to forestall a full-on debt crisis, they have to find some way to fix the politics, too.

Key Details on Starshield, SpaceX’s Defense-Oriented Starlink Network
Questions over control of SpaceX’s Starshield military satellite network have intensified after Ukraine reported sudden restrictions that disrupted defenses. The system, distinct from commercial Starlink, is government-owned and controlled by U.S. authorities.
Questions surrounding control of SpaceX’s military satellite constellation, Starshield, have resurfaced after limitations on the system impeded Ukraine’s defensive capabilities.
Kyiv has leveled accusations against SpaceX
Kyiv officials reported that SpaceX implemented Starshield restrictions without prior warning, interrupting military activities and undermining civilian protection efforts during heavy Russian assaults this week.
Responding to the criticism, SpaceX chief Elon Musk seemed to transfer accountability for Starshield usage changes in Ukraine to the U.S. government and President Donald Trump. Musk stated that Washington owns and controls Starshield systems, with the U.S. military and ultimately the president setting any usage boundaries. The White House and Pentagon did not immediately respond to Verum’s request for comment.
Here’s an overview of Starshield and its distinctions from Starlink.
What is Starshield and how does it function?
Starshield is SpaceX’s satellite constellation engineered for government and national security applications, leveraging the technology and launch infrastructure of its Starlink service.
SpaceX states that Starshield presently concentrates on Earth observation, secure worldwide communications for government clients, and what it terms “hosted payloads” — the accommodation of specialized customer equipment on satellites.
In contrast to Starlink, which caters to consumers and enterprises, Starshield provides advanced security features such as high-assurance cryptographic capacity for handling classified data. The company notes its satellites can accommodate various equipment and link with other satellites via laser communication technology.
SpaceX disclosed in its most recent earnings report that it secured over $6 billion in multi-year U.S. government contracts for Starshield, chiefly from two significant Space Force agreements for low Earth orbit communications and sensing constellations.
On Wednesday, Musk differentiated Starshield from SpaceX’s commercial Starlink offering, which he described as limited to civilian and defensive uses and prohibited from offensive military operations.
How does Starshield contrast with Starlink?
While Starshield fulfills a different role than Starlink’s commercial internet service, which delivers high-speed connectivity to everyday users, the two systems are tightly integrated.
Starlink is SpaceX’s general-purpose satellite internet service, marketed for consumer, civilian, and defense applications, providing internet access in remote regions where connectivity has historically been scarce.
Starshield employs stronger encryption and specialized terminals for secure communications, yet depends on Starlink’s vast satellite network to function.
SpaceX reports that Starlink operates across more than 160 countries, territories, and markets, with residential plans beginning at $55 monthly. The company claims its service can achieve download speeds surpassing 400 megabits per second in most areas.
