An EPIC View of the 2017 Solar Eclipse

Wondrous images, from a million miles out in space, from NASA’s Earth Polychromatic Imaging Camera (EPIC) of the shadow of the moon crossing over North America on Aug. 21, 2017.  EPIC is aboard NOAA’s Deep Space Climate Observatory (DSCOVR), photographing the full sunlit side of Earth every day.  [Image credit: NASA EPIC Team. Video credit: NASA’s Goddard Space Flight Center/Katy Mersmann] Pete Baker

Seven years of Solar Dynamics

It seems like only yesterday that I was noting First Light on Nasa’s Solar Dynamics Observatory [SDO], and the early hours of this morning for ‘three years in three minutes‘ and ‘SDO Year 4‘.  In fact the SDO was launched on 11 Feb 2010, with First Light in April of that year. [Seven long years… – Ed]  Nasa’s Goddard Space Flight Centre have produced a short [3 min 22 sec] video marking the solar sunspot cycle during that time. [Credit: NASA’s … Read more

A bit of perspective…

…with this stunning composite image of the Earth and its moon, courtesy of the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. [Image credit: NASA/JPL-Caltech/Univ. of Arizona] From the associated text This composite image of Earth and its moon, as seen from Mars, combines the best Earth image with the best moon image from four sets of images acquired on Nov. 20, 2016, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter. Each … Read more

Mercury in motion

If you missed yesterday’s rare Mercury transit across the Sun – the last was in 2006, the next in 2019 – then where were you! [Busy… – Ed]  But even if you were paying attention you’re unlikely to have had as wondrous a view as that of Nasa’s Solar Dynamics Observatory. They’ve helpfully released a stunning time-lapse video compressing the entire 7 hour spectacle into a digestible couple of minutes.  I recommend switching to full screen mode and cranking up the volume.  Enjoy!  [Video … Read more

Another view…

Vote… don’t vote…  In the meantime, here’s another in an occasional series of wondrous views from the International Space Station, via the Nasa Crew Earth Observations videos – Sunglint over the Ocean.  [Video courtesy of the Earth Science and Remote Sensing Unit, NASA Johnson Space Center] This video was taken by the Expedition 47 crew on board the International Space Station. The sequence of shots was taken on March 25, 2016 from 11:45:02 to 11:57:17 GMT on a pass over … Read more

New Horizons: Live Briefing

Having survived yesterday’s fly-by, follow the live-briefing from the Nasa New Horizons mission to Pluto as they reveal the first hi-resolution images from the dwarf planet system nearly 5 billion km away. Adds The big news is that Pluto, and Charon, may still be geologically active. There are 3,500metre (11,000feet) high water-ice mountains on the surface of Pluto in a region now called Tombaugh Regio after Pluto’s discoverer, Clyde Tombaugh – some of his ashes are on-board the New Horizons … Read more

New Horizons: Countdown to Pluto

Nasa’s New Horizons mission spacecraft is now within two days journey time to the dwarf planet Pluto and its complex system of 5 moons.  [Image credit: NASA, ESA, and M. Showalter (SETI Institute)]   Travelling at 14km/s, New Horizons’ swift fly-by of the dwarf planet is scheduled to take place on Tuesday 14 July, at exactly 11:49:59 GMT (12:49:59 BST; 07:49:59 EDT), when it will be a mere 12,500km from the surface. At a distance of 4.7 billion km, New … Read more

ISS Night-time Compilation

A brief musical interlude, accompanied by a selection of wondrous time-lapse videos, old and new, from the International Space Station, by NASACrewEarthObs.  Full-screen mode recommended.  Enjoy! [Credit: Image Science and Analysis Laboratory, NASA Johnson Space Center.] The final video clip shows the surprisingly robust sun-grazing Comet Lovejoy as it emerged triumphant from its close encounter with Sol in December 2011.

Fly Over Dwarf Planet Ceres

In March Nasa’s Dawn spacecraft became the first man-made object to go into orbit around a dwarf planet – Ceres, at 950km across, the largest object in the main asteroid  belt.  As I mentioned at the time… [Image credit: Nasa/JPL] Using images taken during Dawn’s first mapping orbit at Ceres, Nasa’s Jet Propulsion Laboratory have produced this stunning, and eerie, animation of flyover views of the heavily cratered world. A new video animation of dwarf planet Ceres, based on images taken … Read more

Raise a glass to Hubble! – Redux

The Hubble Space Telescope celebrates its 25th Anniversary in space today, 24th April, with the release of this wondrous image of the giant star-cluster, Westerlund 2, in the stellar nursery, Gum 29, located 20,000 light-years away in the constellation Carina.  [Image credit: Credit: NASA, ESA, the Hubble Heritage Team (STScI/AURA), A. Nota (ESA/STScI), and the Westerlund 2 Science Team] From the accompanying text to the image. To capture this image, Hubble’s Wide Field Camera 3 pierced through the dusty veil shrouding … Read more

In case you missed the eclipse…

Or, like me, cloud cover obscured the solar eclipse of 20 March 2015.  Here’s probably the best view of this morning’s event, from ESA’s Sun-watching Proba-2 mini-satellite.  [Image credit: ESA/ROB] And via ESA on YouTube. As Europe enjoyed a partial solar eclipse on the morning of Friday 20 March 2015, ESA’s Sun-watching Proba-2 minisatellite had a ringside seat from space. Orbiting Earth once approximately every 100 minutes, Proba-2 caught two eclipses over the course of the morning. Proba-2 used its SWAP imager … Read more

Stargazing the 20 March 2015 Solar Eclipse

The BBC’s Stargazing Live returns tonight, 8pm BBC 2, with three consecutive nights of live programmes to coincide with the total solar eclipse on Friday 20 March 2015.  [It is an annual series! – Ed].  Stargazing Live is, yes.  Not necessarily total solar eclipses, though.  And this solar eclipse is the only one, total or otherwise, to be visible from Europe for the next few years.  ESA’s mini-satellites will have a better view.  But not as good a view as this…   The BBC … Read more

Dawn over Ceres

On Friday afternoon [GMT], ahead of Ireland cricketers’ epic encounter with Zimbabwe, Nasa’s Dawn spacecraft became the first man-made object to go into orbit around a dwarf planet – Ceres, at 950km across, the largest object in the main asteroid belt. [Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA] From the associated text The slim crescent of Ceres smiles back as the dwarf planet awaits the arrival of an emissary from Earth. This image was taken by NASA’s Dawn spacecraft on March 1, 2015, just a few … Read more

“an unforgettable journey across the Red Planet.”

Curiosity may have been on the surface of Mars for over a year, but ESA’s Mars Express has been in orbit around the Red Planet for almost a decade.  It’s one of a number of ways Mars is being observed, up close and personal.  And, like the Hi-RISE camera on Nasa’s Mars Reconnaissance Orbiter, Mars Express has some specialised instruments on-board for that purpose.  Among them is the High Resolution Stereo Camera (HRSC).  The stunning 3D images in this video were taken by that camera.   The video was released … Read more

Time-lapse: Earth

As the Guardian’s GrrlScientist says, “Wow. Just wow.”  And, “Oh, I recommend “full screen” mode.” Indeed.

A year of Curiosity

One year ago, after “seven minutes of terror“, Nasa’s Mars Science Laboratory, the 900kg rover Curiosity, landed safely on the Red Planet and was soon taking a look around.   [Image Credit: NASA/JPL-Caltech/Malin Space Science Systems]  Full image and caption here. This scene combines seven images from the telephoto-lens camera on the right side of the Mast Camera (Mastcam) instrument on NASA’s Mars rover Curiosity. The component images were taken between 11:39 and 11:43 a.m., local solar time, on 343rd Martian day, or … Read more

“There’s no place like home…”

I didn’t ‘Wave at Saturn’ on 19 July when the Cassini probe, orbiting the gas giant, was taking a high-definition image of the view back home.  I don’t think it encouraged a proper sense of perspective…  But the resultant image is stunning. [Image Credit: NASA/JPL-Caltech/Space Science Institute] It’s not the first time Cassini has looked home.  Nor is it the only stunning image the probe has provided.  But, as those involved pointed out “We can’t see individual continents or people in this … Read more

Three Years of SDO Data – Narrated

If you enjoyed the recent video from Nasa’s Solar Dynamics Observatory (SDO) – “Three years in three minutes” – but would have liked more of an explanation of what was going on with our own local star… here it is again!  This time, though, extended, and narrated by NASA’s Goddard Space Flight Center heliophysicist Alex Young.
