Astrophysicists Confirm The Faintest Galaxy Ever Seen In The Early Universe

by SpaceRef June 2, 2023July 15, 2024

The final observing campaign of NASA's Kepler Space Telescope lasted only a month. As the spacecraft began to run low on attitude control fuel, it couldn’t maintain its position long enough to collect useful observations. In the end, astronomers only had about seven days of high-quality data. A research team worked with a group of citizen scientists and professional astronomers and found three planets in the last bit of data. CREDIT NASA/JPL-Caltech (K. Walbolt)

Astronomers Discover Planets In NASA Kepler’s Final Days Of Observations

Light curves of each of the three planet candidate systems. Top row: The full 7.25-d high-quality discovery light curves of each of our systems are shown on the top produced via the process outlined in Section 2.1. Bottom row: Zoomed-in light curves near the three single transits, along with the best-fitting transit model from Section 3.2. The best-fitting parameters are outlined in Table 4. We detected additional transits of two of these three planet candidates, which are shown in Fig. 2. We also note that there are two small dipping features in the light curve of EPIC 245978988 that can be seen around t = 3538 d and t = 3543.5 d. We conclude that these are systematic because they are not robust to changing data reduction parameters. -- Royal Astronomical Society

Astronomers Discover The Last Planets Seen By Kepler Space Telescope

Imaging observations centered on WD 2226-210. Left: the Helix Nebula observed at 70 μm by Herschel/Photodetector Array Camera and Spectrometer (PACS; Van de Steene et al. 2015). The image has been smoothed with a Gaussian kernel with FWHM 5farcs4 to enhance its appearance. The region centered on WD 2226-210 and covered by the four cutaway panels to the right is denoted by the white boxes. Right: the top row is Spitzer/MIPS 24 μm (Su et al. 2007; left) and SOFIA/HAWC+ 54 μm (right), and the bottom row is Herschel/PACS 70 μm (left) and ALMA Band 6 (right). Only the Spitzer and Herschel observations detect the excess emission associated with the white dwarf. The orientation of all images is north up, east left. The instrument beam for each observation is denoted by the white shaded ellipse in the bottom-left corner of the panel.

SOFIA Helps Reveal a Destroyed Planetary System

At our upper left is the NGC 346 star cluster. Next, in our lower left of the two-by-two grid, is a spiral galaxy like our own Milky Way, known as Messier 74. At our upper right of the two-by-two grid is another spiral galaxy called NGC 1672. Finally, at our lower right of the two-by-two grid, is the Eagle Nebula, often referred to as the "Pillars of Creation". -- NASA

Chandra And Webb Space Telescope Combine Imagery For Arresting Views

Thousands of bright points of light on a black background fill the field of view. They appear somewhat more concentrated near the centre of the image. They have a variety of colours, with the most prominent stars appearing blue or yellow-orange. The brighter stars also display four diffraction spikes.] Credit: ESA/Hubble & NASA

NASA Completes Heart of Roman Space Telescope’s Primary Instrument

LP 791-18 d, shown here in an artist's concept, is an Earth-size world about 90 light-years away. The gravitational tug from a more massive planet in the system, shown as a blue disk in the background, may result in internal heating and volcanic eruptions – as much as Jupiter’s moon Io, the most geologically active body in the solar system. Astronomers discovered and studied the planet using data from NASA’s Spitzer Space Telescope and TESS (Transiting Exoplanet Survey Satellite) along with many other observatories.
