Washington, D.C. – Observers in the Northern Hemisphere are hoping to catch a glimpse of Comet NEOWISE as it zips through the inner solar system before it speeds away into the depths of space.
Discovered on March 27th, 2020 by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission, Comet NEOWISE is putting on a dazzling display for skywatchers before it disappears, not to be seen again for another 6,800 years.
Pasadena, CA – NASA says Planets form from gas and dust particles swirling around baby stars in enormous spinning disks. But because this process takes millions of years, scientists can only learn about these disks by finding and studying a lot of different examples.
Through a project called Disk Detective, you can help. Anyone, regardless of background or prior knowledge, can assist scientists in figuring out the mysteries of planet formation. Disk Detective is an example of citizen science, a collaboration between professional scientists and members of the public.
Pasadena, CA – With the help of citizen scientists, astronomers have discovered two highly unusual brown dwarfs, balls of gas that are not massive enough to power themselves the way stars do.
Participants in the NASA-funded Backyard Worlds: Planet 9 project helped lead scientists to these bizarre objects, using data from NASA’s Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) satellite along with all-sky observations collected between 2009 and 2011 under its previous moniker, WISE. Backyard Worlds: Planet 9 is an example of “citizen science,” a collaboration between professional scientists and members of the public.
Pasadena, CA – NASA says a comet visiting from the most distant parts of our solar system is putting on a spectacular nighttime display. Named Comet C/2020 F3 NEOWISE, the comet made its once-in-our-lifetimes close approach to the Sun on July 3rd, 2020, and will cross outside Earth’s orbit on its way back to the outer parts of the solar system by mid-August.
The comet cruised just inside Mercury’s orbit on July 3rd. This very close passage by the Sun is cooking the comet’s outermost layers, causing gas and dust to erupt off the icy surface and creating a large tail of debris. And yet the comet has managed to survive this intense roasting.

Pasadena, CA – Nearly all asteroids are so far away and so small that the astronomical community only knows them as moving points of light. The rare exceptions are asteroids that have been visited by spacecraft, a small number of large asteroids resolved by NASA’s Hubble Space Telescope or large ground-based telescopes, or those that have come close enough for radar imaging.
When seen by optical telescopes, these individual sources of reflected sunlight can provide some very valuable but also very basic information — for example, the asteroid’s orbit, a ballpark estimate of its size, sometimes an approximation of its shape, and perhaps an idea of its physical makeup.
NASA’s WISE spacecraft reveals nearly five times more comets have passed the Sun then previously predicted

Pasadena, CA – Comets that take more than 200 years to make one revolution around the Sun are notoriously difficult to study. Because they spend most of their time far from our area of the solar system, many “long-period comets” will never approach the Sun in a person’s lifetime.
In fact, those that travel inward from the Oort Cloud — a group of icy bodies beginning roughly 186 billion miles (300 billion kilometers) away from the Sun — can have periods of thousands or even millions of years.
NASA’s WISE spacecraft, scanning the entire sky at infrared wavelengths, has delivered new insights about these distant wanderers.
NASA’s Wide-field Infrared Survey Explorer (WISE) observes one of the Brightest Galaxies destroying itself

Pasadena, CA – In a far-off galaxy, 12.4 billion light-years from Earth, a ravenous black hole is devouring galactic grub. Its feeding frenzy produces so much energy, it stirs up gas across its entire galaxy.
“It is like a pot of boiling water being heated up by a nuclear reactor in the center,” said Tanio Diaz-Santos of the Universidad Diego Portales in Santiago, Chile, lead author of a new study about this galaxy.
NASA’s Wide-field Infrared Survey Explorer spacecraft data shows Carbon Monoxide, Carbon Dioxide in Comets

Pasadena, CA – After its launch in 2009, NASA’s NEOWISE spacecraft observed 163 comets during the WISE/NEOWISE prime mission. This sample from the space telescope represents the largest infrared survey of comets to date.
Data from the survey are giving new insights into the dust, comet nucleus sizes, and production rates for difficult-to-observe gases like carbon dioxide and carbon monoxide. Results of the NEOWISE census of comets were recently published in the Astrophysical Journal.

Pasadena, CA – Imagine trying to create a map of your house while confined to only the living room. You might peek through the doors into other rooms or look for light spilling in through the windows. But, in the end, the walls and lack of visibility would largely prevent you from seeing the big picture.
The job of mapping our own Milky Way galaxy from planet Earth, situated about two-thirds of the way out from the galaxy’s center, is similarly difficult. Clouds of dust permeate the Milky Way, blocking our view of the galaxy’s stars.
NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) images now available Online to the Public

Pasadena, CA – Millions of images of celestial objects, including asteroids, observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft now are available online to the public. The data was collected following the restart of the asteroid-seeking spacecraft in December 2013 after a lengthy hibernation.
The collection of millions of infrared images and billions of infrared measurements of asteroids, stars, galaxies and quasars spans data obtained between December 13th, 2013, and December 13th, 2014.
