  • Even from three billion miles away, Pluto still knows how to be romantic. 
On Jul. 13, 2015, the New Horizons spacecraft sent us this love note of one of Pluto's most dominant features. The “heart,” estimated to be 1,000 miles (1,600 kilometers) across at its widest point, rests just above the equator. (The angle of view displays mostly the northern hemisphere.) The heart’s diameter is about the same distance as from Denver to Chicago, in America’s heartland.

New Horizons traveled nearly a decade to receive its summer valentine, launching on Jan. 19, 2006 — and is still collecting important data for us. On New Year’s Day 2019, New Horizons flew by the most distant object ever visited by a spacecraft: Ultima Thule.

  • It’s so hard to say goodbye! 👋

Designed to last just 90 Martian days and travel 1,100 yards, our Mars Opportunity rover explored the surface of the Red Planet and broke records during its 15-year mission. It vastly surpassed all expectations in its endurance, scientific value and longevity. In addition to exceeding its life expectancy by 60 times, the rover traveled more than 28 miles by the time it reached its most appropriate final resting spot on Mars – Perseverance Valley.

Today, we bid farewell to the rover that stopped communicating with Earth when a severe Mars-wide dust storm blanketed its location in June 2018. 
In this image from 2010, Opportunity used its navigation camera for this northward view of tracks the rover left on a drive from one energy-favorable position on a sand ripple to another. The tracks that Opportunity left on the Martian soil will pave the way for future robotic and human exploration of the Red Planet.

  • Sand dunes...on Mars! 🔴 With an elongated crescent form, these "barchan dunes" are located near Nili Patera and are formed by the continuous action of the wind blowing in the same direction. 
The orientation of these dunes tells us that the prevailing wind blows from right to left (east to west). The wind is continuously moving sand grains up the longer dune slope, towards the top. The small ripples on the slope are caused by this movement. When the sand grains arrive at the top, they fall down the steeper and shorter slope, which as a consequence, has no ripples. It is this gradual sand movement that causes the dunes to slowly move over time.

  • The @NASAHubble Space Telescope doesn’t usually get much assistance from its celestial subjects — but to take this image, the telescope opted for teamwork and made good use of a fascinating cosmic phenomenon known as gravitational lensing.

This effect works when the gravitational influence of a massive object, such as the galaxy cluster in this image, is so colossal that it warps the surrounding space, causing nearby light to travel along distorted paths. The massive object is effectively turned into a giant magnifying glass, bending and amplifying the light traveling from more distant galaxies lying behind it.

In this particular case, astronomers used the foreground galaxy cluster to study star formation in galaxies lying so far away that their light has taken up to 11.5 billion years to reach Earth. These galaxies formed at a very early stage in the lifetime of the universe, giving astronomers a rare glimpse into the beginning of the cosmos. Despite the distance of these galaxies, the lensing effects allowed astronomers to work out the sizes, luminosities, star formation rates and stellar populations of individual star-forming clumps within these galaxies — quite an achievement!

  • Each year, we hold a Day of Remembrance. Today, #NASARemembers the crews of Apollo 1 and space shuttles Challenger and Columbia, as well as other colleagues who have lost their lives advancing the frontiers of space exploration. 
This photo of sunrise was captured by the crew of Space Shuttle Columbia on Jan. 22, 2003 from the crew cabin during Flight Day 7. After completing a successful 16-day mission, Columbia and her crew were lost during reentry over East Texas at about 9 a.m. EST, 16 minutes before the scheduled touchdown.

Join us in honoring the women and men who gave their lives in the pursuit of space exploration.

  • When four giant galaxy clusters collide, the aftermath reveals brilliant magenta swirls of hot gas from optical and radio data. At a distance of about 3.5 billion light years, this system is dubbed "Pandora's Cluster" by astronomers as because all of the different structures found within it. 
This composite view contains X-ray data from our Chandra X-Ray Observatory (@NASAChandraXRay) showing hot gas in blue, optical data from Subaru and the Very Large Telescope in red, green and blue, and radio data from the NSF's Karl G. Jansky Very Large Array in red.

  • Spirals! The Triangulum Galaxy, seen here, is a spiral galaxy about 3 million light years from Earth belonging to the group of galaxies that includes the Milky Way and Andromeda galaxies. 
Chandra X-Ray Observatory's (@NASAChandraXRay) data in pink reveals a diverse range of objects including neutron stars and black holes that are pulling material from a companion star, and supernova remnants. An optical image from amateur astronomer Warren Keller in red, green, and blue shows the majestic arms of this spiral galaxy that in many ways is a cousin to our own Milky Way.

  • We hope you’re having a Stellar Saturday! 🌟

A glimpse from the @NASAHubble Space Telescope reveals an ancient, glimmering ball of stars. This globular cluster of stars moves slowly through space on the outskirts of the Large Magellanic Cloud, one of our closest galactic neighbors. 
This cluster is certainly one for extremes. It has a mass equivalent to roughly 140,000 Suns and and an age of around 13.1 billion years — making it almost as old as the universe itself. 
The stars in this cluster are not only dazzling — they are also indispensable tools. Some of these particular stars have well-defined luminosities, meaning that astronomers know the total amount of energy they emit. By comparing star luminosities, we can calculate the distances to these stars!

  • 🔎 Beautiful landforms of Mars! 
The camera (@UAHiRISE) aboard our Mars Reconnaissance Orbiter spacecraft zooms in for a close look at a Martian crater, where gullies have eroded the slopes and carried sediment down, forming debris aprons. Numerous fractures run perpendicular to the slopes, and in the upper regions, jagged outcrops cast long shadows from the ridges to the gully floor.
