Topic: Interstellar Space
The call to Voyager 2 was a test of new hardware recently installed on Deep Space Station 43, the only dish in the world that can send commands to Voyager 2. ![]() Crews conduct critical upgrades and repairs to the 70-meter-wide (230-foot-wide) radio antenna Deep Space Station 43 in Canberra, Australia. In this image, one of the antenna’s white feed cones (which house portions of the antenna receivers) is being moved by a crane.

NASA’s New Horizons spacecraft measurements reveals loads of Hydrogen in Interstellar Medium
In this stellar no-man’s land, particles and light shed by our galaxy’s 100 billion stars jostle with ancient remnants of the big bang. This mixture, the stuff between the stars, is known as the interstellar medium. Its contents record our solar system’s distant past and may foretell hints of its future. «Read the rest of this article» Sections: Technology | No Comments
NASA’s SOFIA telescope discovers Pulsing Stars ejecting Carbon Gas, Dust into Interstellar Space
The Stratospheric Observatory for Infrared Astronomy, SOFIA, examined several types of pulsating stars in our Milky Way galaxy, watching as some spewed carbon, a key ingredient of life as we know it, into interstellar space. ![]() Image of a carbon star known as CW Leonis or IRC+10216 taken by the Herschel Space Observatory. SOFIA found that some carbon stars with especially strong pulsations, called Mira variables, distribute large amounts of carbon to interstellar space where it can be used as a building block for life and other complex structures.

NASA’s Hubble Space Telescope observes Quasar emitting Energy across the Galaxy
Quasars are extremely remote celestial objects, emitting exceptionally large amounts of energy. Quasars contain supermassive black holes fueled by infalling matter that can shine 1,000 times brighter than their host galaxies of hundreds of billions of stars. ![]() This is an illustration of a distant galaxy with an active quasar at its center. A quasar emits exceptionally large amounts of energy generated by a supermassive black hole fueled by infalling matter. Using the unique capabilities of the Hubble Space Telescope, astronomers have discovered that blistering radiation pressure from the vicinity of the black hole pushes material away from the galaxy’s center at a fraction of the speed of light.

NASA’s Voyager 2 Communications to be affected by Deep Space Antenna Upgrades
During this time, the Voyager team will still be able to receive science data from Voyager 2 on its mission to explore the outermost edge of the Sun’s domain and beyond. ![]() DSS43 is a 70-meter-wide (230-feet-wide) radio antenna at the Deep Space Network’s Canberra facility in Australia. It is the only antenna that can send commands to the Voyager 2 spacecraft. (NASA/Canberra Deep Space Communication Complex) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Voyager 2 spacecraft entered Interstellar Space One Year Ago Today
Today, five new research papers in the journal Nature Astronomy describe what scientists observed during and since Voyager 2’s historic crossing. ![]() This artist’s concept shows one of NASA’s Voyager spacecraft entering interstellar space, or the space between stars. This region is dominated by plasma ejected by the death of giant stars millions of years ago. Hotter, sparser plasma fills the environment inside our solar bubble.

NASA’s Voyager 2 Probe leaves Heliosphere, enters Interstellar SpaceNASA Jet Propulsion Laboratory
Members of NASA’s Voyager team will discuss the findings at a news conference at 10:00am CST (8:00am PST) on Monday, December 10th at the meeting of the American Geophysical Union (AGU) in Washington. The news conference will stream live on the agency’s website. ![]() This illustration shows the position of NASA’s Voyager 1 and Voyager 2 probes, outside of the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 exited the heliosphere in August 2012. Voyager 2 exited at a different location in November 2018. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA’s Voyager 2 probe maybe about to enter Interstellar SpaceNASA’s Jet Propulsion Laboratory
Since 2007 the probe has been traveling through the outermost layer of the heliosphere — the vast bubble around the Sun and the planets dominated by solar material and magnetic fields. Voyager scientists have been watching for the spacecraft to reach the outer boundary of the heliosphere, known as the heliopause. Once Voyager 2 exits the heliosphere, it will become the second human-made object, after Voyager 1, to enter interstellar space. ![]() This graphic shows the position of the Voyager 1 and Voyager 2 probes relative to the heliosphere, a protective bubble created by the Sun that extends well past the orbit of Pluto. Voyager 1 crossed the heliopause, or the edge of the heliosphere, in 2012. Voyager 2 is still in the heliosheath, or the outermost part of the heliosphere.

NASA 2017 HighlightsWritten by Jen Rae Wang / Allard Beutel
One of the numerous NASA-related activities and actions the Trump Administration did in 2017 was to reconstitute the National Space Council. During its first meeting on October 5th, Vice President Mike Pence directed NASA to develop a plan to help extend human exploration across our solar system, and return astronauts to the Moon in preparation for human missions to Mars and other destinations. «Read the rest of this article» Sections: Technology | No Comments
NASA uses backup Thrusters to orient Voyager 1 SpacecraftWritten by Elizabeth Landau
Voyager 1, NASA’s farthest and fastest spacecraft, is the only human-made object in interstellar space, the environment between the stars. The spacecraft, which has been flying for 40 years, relies on small devices called thrusters to orient itself so it can communicate with Earth. ![]() The Voyager team is able to use a set of four backup thrusters, dormant since 1980. They are located on the back side of the spacecraft in this orientation. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
