Put on your 3-D glasses for this ride over asteroid Vesta. New year, new Moon; midnight meteors; and Mars rises. its final destination, a million miles from Earth, last month. } else { The comet might be glimpsed with the eye alone, the tricky thing will be to catch it at just the right time after sunset, not too early (when bright twilight will wash it out) and not too late (when it will have set). }, 300) (MTU) & For insight on what to expect in the months ahead and how to follow along, we hear from Alexandra Lockwood, project scientist for Webb science communications at the Space Telescope Science Institute: Words cant describe the pride and excitement the Webb team is feeling right now. Then share the results with your friends on social media using #Hubble30. Jupiter's Great Red Spot, seen here in an amazing mosaic composite image from artist and filmmaker Michael Benson, is a massive cyclone about twice the size of Earth. Cassini mission planners created this animation to showcase Cassini's final 22 orbits - the mission's Grand Finale. It still might become the brightest comet of 2021! Once Jupiter departs at the end of February, the post-sunset sky will be essentially devoid of naked-eye planets until August, when Saturn will start rising in the east around sunset. Not only would that big burn cost a lot of propellant, it would be impossible because it would require Webb to turn 180 degrees in order to thrust toward the Sun, which would have exposed its telescope optics and instruments directly to the Sun, thus overheating their structures and literally melting the glue that holds them together. Discover the cosmos! Furthermore, by orbiting rather than being exactly at L2, Webb will never have the Sun eclipsed by Earth, which is necessary for Webbs thermal stability and for power generation. Toss a note in a bottle and hope that it helps Across the top of the frame are the stars and nebulae along the plane of our own Milky Way Galaxy. New year, new Moon; midnight meteors; and Mars rises. By that we mean that this comet takes tens of thousands of years to complete an orbit around the sun. The Webb mission operations team has given the go-ahead to move forward with the extension of its starboard primary mirror panel. Is it possible to observe this comets motion. Impressive solar filament eruption - January 20, 2023. Following Webb's arrival at its orbital destination around Lagrange Point 2 (L2) on Jan. 24, the mission operations team began working its way through a critical series of steps: powering on all the science instruments, turning off heaters to begin a long cooldown process, and ultimately capturing the first photons on Webb's primary camera to enable a months-long alignment of the telescope. An amazing feature of this celestial visitor is that its an ultrafast comet. The Ariane 5 targeted Webb so accurately that our first and most critical burn was smaller than we had to plan and design for, leaving more fuel for an extended mission!, Karen Richon, Webb Flight Dynamics lead engineer, NASAs Goddard Space Flight Center. Now that the action-packed deployment sequence is over, we are moving into a much slower, yet deliberate, phase of the commissioning process. Bob King pointed out at Skyandtelescope.com, See more Comet Leonard photos at EarthSky Community Photos. And because L2 is a location of gravitational equilibrium, it is easy for Webb to maintain an orbit there.
