NASA's intrepid Voyager 2 probe crosses into interstellar space 2018-12-10T05:00:00Z But subsequent measurements from IBEX, Cassini, and Voyager point to a more rounded heliosphere, and recent modeling suggest it is concave on one side, like a croissant. ‘Voyager on steroids.’ Mission would probe mysterious region beyond our Solar System 2022-07-27T04:00:00Z In some models, as the heliosphere cruises along at 450,000 mph, interstellar matter flows smoothly past it, like water around the bow of a ship, resulting in an overall cometlike shape. Record-Breaking Voyager Spacecraft Begin to Power Down 2022-06-16T04:00:00Z The most obvious explanation for this disparity is that our solar system’s heliosphere is not perfectly spherical—instead it is oddly shaped and asymmetric, perhaps due to the influence of the Milky Way’s magnetic field. Voyager 2 Spacecraft Enters Interstellar Space 2018-12-10T05:00:00Z The heliosphere is a bubble of gases emanating outward from our sun, and it is buffeted by winds of interstellar particles that blow through the Milky Way.

The Echoes of Hearts Long Silenced 2014-12-15T05:00:00Z If they’re right, the spacecraft will detect a reversal in the magnetic field, proving that it’s still in the heliosphere. Voyager Scientists Disagree On Whether Craft Has Reached Interstellar Space 2014-07-24T04:00:00Z If the spacecraft is still inside the heliosphere, they say, it should encounter something called the “current sheet,” a place where the Sun’s magnetic field flips from north to south.

Voyager 1 is officially the first manmade object to enter interstellar space 2014-07-10T04:00:00Z Back in March, scientists had outlined their results showing that Nasa's Voyager-1 spacecraft had left the heliosphere. In pictures: Science news highlights of 2013 2013-12-26T02:45:10Z Gurnett also estimates that the plasma density in the local interstellar cloud that surrounding the heliosphere will continue to click up for about another year. NASA's Voyager 1 Mission Far From Over 2013-09-29T09:44:00Z This is not a static number: Our sun is orbiting the galaxy at 125 miles per second; its interstellar environment — and thus the size and shape of its heliosphere — is constantly in flux. The Loyal Engineers Steering NASA’s Voyager Probes Across the Universe 2017-08-03T04:00:00Z The results show that Voyager 1 is surrounded by plasma more than 40 times denser than it encountered earlier, when it was in the heliosphere. Voyager 1 Leaves the Solar System for Real This Time 2013-09-16T13:18:03.730Z The place where the Sun’s particles dominate is known as the heliosphere, but the boundary region between heliosphere and interstellar space—a region known as the heliopause—is a turbulent and complex place. Adios, Voyager 1 2013-09-12T20:05:22Z Stone and other scientists believe Voyager is in a previously unknown region, dubbed a "magnetic highway," that exists between the heliosphere and interstellar space.

Voyager 1 Returns Surprising Data about an Unexplored Region of Deep Space 2013-06-27T19:15:08.627Z The dimensions and nature of the heliosphere are not a wholly esoteric matter. Voyager 1 finds that edge of solar system isn’t as defined as scientists once thought 2013-06-27T18:25:18Z Voyager 1 is still strongly influenced by the flow of the interstellar plasma around the heliosphere. NASA's Voyager 1 Mission Far From Over 2013-09-29T09:44:00Z Five years ago, Voyager 1 reached the boundary where the heliosphere gives way to interstellar space, a region as novel to us — and potentially relevant — as the Pacific was to Europeans 500 years ago. The Loyal Engineers Steering NASA’s Voyager Probes Across the Universe 2017-08-03T04:00:00Z Rather, it’s defined by the heliosphere, the vast windstorm of charged particles that stream outward from the sun. Voyager I: On the Solar System's Exit Ramp 2013-06-28T11:50:28Z Someday soon, it is expected, Voyager 1 will become the first spacecraft to exit the heliosphere—the bubble of solar plasma encasing the sun and planets—and enter the interstellar medium.

Voyager 1 Reaches Solar System's Edge 2012-12-05T14:35:00Z In 1961, Eugene Parker, the renowned astrophysicist who first predicted the existence of a heliosphere, hypothesized that it might look like a comet — compressed in front with a tail in back. The Loyal Engineers Steering NASA’s Voyager Probes Across the Universe 2017-08-03T04:00:00Z When the sun is emitting more radiation, it generates a strong external magnetic field, which swaddles the solar system in the "heliosphere"—a shield against GRCs.
