Webb will perform its science mission while orbiting a location in space, called the second Lagrange point, or L2 for short. L2 is located one million miles from Earth. As Webb orbits L2, the telescope stays in line with Earth as it travels around the Sun. L2 is a point where the gravitational influences of the Earth and Sun balance the centripetal force of a small object orbiting with them. The telescope's optics and instruments need to be kept very cold to be able to observe the very faint infrared signals of very distant objects clearly. This location is perfect for Webb's sunshield to block out light and heat from the Sun, Earth, and Moon. Unlike the Hubble Space Telescope, Webb's orbit keeps the spacecraft out of the Earth's shadow making L2 a thermally stable location for the observatory to operate at. Webb will operate within its field of regard. The \"field of regard\" refers to the angles the telescope can move while staying in the shadow of the Sun. Each of Webb's instruments has its own field of view. The field of view is the area of sky an instrument can observe. Webb's fine steering mirror is moved so that an object can be observed by the different instruments. This prevents the whole telescope from having to repoint itself to do so. The Webb Telescope’s commissioning process will be complete approximately six months after launch, at which time Webb start its science mission.

NASA’s Parker Solar Probe is in the midst of intense environmental testing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, in preparation for its journey to the Sun. These tests have simulated the noise and shaking the spacecraft will experience during its launch from Cape Canaveral, Florida, scheduled for July 31, 2018.Parker Solar Probe’s integration and testing team must check over the spacecraft and systems to make sure everything is still in optimal working condition after experiencing these rigorous conditions – including a check of the solar arrays, which will provide electrical power to the spacecraft.Parker Solar Probe will explore the Sun's outer atmosphere and make critical observations that will answer decades-old questions about the physics of stars. The resulting data will also help improve how we forecast major eruptions on the Sun and subsequent space weather events that can impact life on Earth, as well as satellites and astronauts in space.

The event, known as a transit, occurs when Mercury passes directly between Earth and the sun. This rare phenomenon will cause Mercury to look like a black dot gliding across the sun’s face. Mercury’s last transit was in 2006, and it won’t happen again until 2019!Starting at 7:12 a.m. EDT, Mercury will spend more than seven hours travelling across the sun. NASA’s Solar Dynamics Observatory will take the first near real time, ultra-high definition images ever for this event. This is also an opportunity for NASA scientists to fine tune the spacecraft’s cameras, using a method that can only be done during a transit. NASA scientists are available Monday, May 9 from 6:00 a.m. – 11:30 a.m. EDT to show your viewers amazing images of this event as it unfolds. Scientists will also share why transits are important, and how they’re being used to learn more about planets in our solar system—and beyond. Scientists have been using transits for hundreds of years to study the planets in our solar system. When a planet crosses in front of the sun, it causes the sun’s brightness to dim. Scientists can measure similar brightness dips from other stars to find planets orbiting them, and can calculate their sizes, how far away the planets are from their stars, and even get hints of what they’re made of. Upcoming NASA missions will watch for transits outside our solar system in order to find new planets, including some that could resemble Earth.****To book a window***Contact Claire Saravia – claire.g.desaravia@nasa.govSuggested questions: 1.Mercury is trekking across the sun today for the first time in 10 years. How can we see this transit?2.Why are transits so important to astronomers? 3.Why does NASA watch the sun?4.NASA is using the transit method to study planets beyond our solar system. What do we expect to learn from future missions doing this? 5.Where can we learn more?

These oppositely pointing magnetic fields are separated by a layer of current called the heliospheric current sheet. Due to the tilt of the magnetic axis in relation to the axis of rotation of the Sun, the heliospheric current sheet flaps like a flag in the wind. The flapping current sheet separates regions of oppositely pointing magnetic field, called sectors. As the solar wind speed decreases past the termination shock, the sectors squeeze together, bringing regions of opposite magnetic field closer to each other. The Voyager spacecraft have now found that when the separation of sectors becomes very small, the sectored magnetic field breaks up into a sea of nested \"magnetic bubbles\" in a phenomenon called magnetic reconnection. The region of nested bubbles is carried by the solar wind to the north and south filling out the entire front region of the heliopause and the sector region in the heliosheath.This discovery has prompted a complete revision of what the heliosheath region looks like. The smooth, streamlined look is gone, replaced with a bubbly, frothy outer layer. More animations about the Voyager magnetic bubbles discovery are available. || ", "hits": 104 }, { "id": 3696, "url": "https://svs.gsfc.nasa.gov/3696/", "result_type": "Visualization", "release_date": "2010-04-21T14:15:00-04:00", "title": "SDO/HMI Continuum Full Disk View - March 29, 2010", "description": "This early sequence of HMI images from SDO focuses on a large sunspot group of Solar Cycle 24. || ", "hits": 85 }, { "id": 3705, "url": "https://svs.gsfc.nasa.gov/3705/", "result_type": "Visualization", "release_date": "2010-04-21T14:15:00-04:00", "title": "SDO/HMI Magnetogram Sunspot Close-Up - March 29, 2010", "description": "This early sequence of images from the HMI imager is processed to reveal the magnetic field structure (magnetogram).
