As of 2019, only five space probes are leaving the solar system: Pioneer 10, Pioneer 11, Voyager 1, Voyager 2 and New Horizons. The Voyagers already left the solar system and entered the interstellar space (Voyager 1 on August 25, 2012, and Voyager 2 on November 5, 2018. The others also will leave the heliosphere Notes 1 and reach the interstellar space in a few years.
All of these spacecraft are launched by NASA.

Margaret Hamilton is not only one of the first software developers, but she also literally created the term “Software Engineering” to describe her work. The code she wrote successfully put humans on the moon for the first time.

A beautiful photo showing the first flower grown in space (a zinnia flower) with our beautiful Earth in the background. Now retired NASA astronaut Scott Kelly shared photographs of a blooming zinnia flower in the Veggie plant growth system aboard the International Space Station on his Twitter account back in 2016.

Launched by NASA on September 5, 1977, to study the outer solar system, the Voyager 1 is the furthest human-made object from Earth. As of January 10, 2019, the space probe is more than 13,491,481,615 miles (21,712,434,988 km) away from our home planet. It is also moving away at a speed of 38,026.77 mph (61,198.15 km/h) relative to the Sun. But, thanks to NASA’s Deep Space Network (DSN) Notes 1, we can still communicate with it (also with its sister, Voyager 2). But how far can Voyager 1 go before we lose communication?
The video published by the Primal Space channel below looks at how we communicate with Voyager and when it will eventually stop receiving our signals.

A microgravity environment is a perfect place to demonstrate basic physics, i.e. Newton’s laws of motion. In the videos published by the NASA Johnson channel, astronauts aboard the International Space Station (ISS) just do that.

A beautiful Ultima Thule image, taken by the Long Range Reconnaissance Imager (LORRI) aboard NASA’s New Horizons spacecraft in original context against a starry background (i.e., not zoomed in).

In January 2015, NASA released the largest image ever of the Andromeda galaxy, called the Panchromatic Hubble Andromeda Treasury (PHAT), taken by the Hubble telescope. This composite image involved thousands of observations, hundreds of fields, spanned about a third of the galaxy and resolved over 100 million stars.
Totaling 1.5 billion pixels and requiring 4.3 gigabytes of disk space, this photo provides a detailed glimpse at the sheer scale of our nearest galactic neighbor.
Using this gigantic image, filmmaker Dave Achtemichuk created an unforgettable interactive experience.

In December 2018, NASA’s Mars InSight Lander recorded the sounds of Mars for the first time ever. Musician Andrew Huang made music using the real Mars sounds.
