Recently, two powerful earthquakes struck Venezuela.
NASA satellites captured imagery and data that are supporting response efforts. This NISAR map shows how the quakes shifted the land surface. Explore more: go.nasa.gov/4v9HTcx

Tonight's full Moon has an atmosphere too — just extraordinarily thin. With about a quadrillion times fewer molecules in a given space than Earth's, it’s so sparse that space rocks strike the surface directly instead of burning up! go.nasa.gov/4f5xx8D 📸 NASA/Bill Dunford
When you wish upon a star (dune)… ⭐️ These windswept sand formations, known as star or pyramid dunes, are a distinctive feature of the Sahara and have sharp multidirectional ridges. They form when the wind transports and deposits fine sand, forming mounds of sediment.

- Breakups are hard 💔 Unless it’s stuff breaking up in Earth’s atmosphere. Then it’s just cool! A @Space_Station astronaut captured an object breaking up in the atmosphere on April 27. It could have been part of a rocket, satellite, other human-made space debris, or a meteor.
- Seems like everyone’s watching Fiji right now… 👀🏝️ Even @NASA satellites! NASA has a fleet of more than 20 satellites that study our home planet and capture images — including this one of the islands of Fiji, which are home to a certain iconic villa.
- Dengue, which is spread by mosquitoes, is a serious health threat in Puerto Rico and a growing concern in parts of the U.S. 🦟 Scientists are using @NASA data to track the environmental conditions linked to dengue and improve forecasts of dengue risk in Puerto Rico.
- Happy summer solstice ☀️ Today marks the start of astronomical summer in the Northern Hemisphere and the longest stretch of daylight. It’s the day the Northern hemisphere is most tilted toward the Sun. go.nasa.gov/4eRPura
- NASA Earth repostedNASA has selected the DAPHNE mission to study how Earth’s atmosphere drives space weather, helping improve predictions that protect tech and astronauts. Twin satellites will launch no earlier than 2029. More: go.nasa.gov/4vf3LE5
- A NASA sensor is helping firefighters stay safe — and gathering critical science data! 🔥👨🚒 NASA’s FireSense project installed the sensors on fire bulldozers to alert the firefighters driving them when their surroundings are getting too hot.
This work is part of a collaboration between @NASA FireSense and @ALForestryComm. The teams are planning to add another NASA science instrument to the fire dozers to measure temperature, spread rate, flame length, fire convection, and gas emissions. - Watch the colors change. This timelapse of Landsat and Sentinel-2 satellite images shows the evaporation process at Chile’s Salar de Atacama, the country's largest salt flat and a major source of the global lithium supply.

Even from afar, wildfires are creating unhealthy air. A NASA-supported study found wildfires have worsened ground-level ozone, or smog, across the U.S., with larger changes in the West and Midwest. Wildfires can increase surface ozone thousands of miles away from active fires.
