Gear up for Mars and Jupiter’s great coming-together

5 August 2024 Mark Armstrong

Mars and Jupiter lie less than a degree apart on the mornings of 14th and 15th August, providing a great spectacle for both visual observers and imagers.

Splashes of colour illustrate the clear difference between the two most populous type of bright nebulae in our Milky Way Galaxy, emission and reflection nebulae.

Triple T-Tauri

This cavernous nebula is home to a bundle of young stars, specifically a triple system of T-Tauri stars.

Forming stars like the old days

In this image, JWST strips away the gas that is transparent at infrared wavelengths, and reveals a skeleton of dusty ribbons that are part of the material that is flowing onto the young stars as they grow.

A matter of perspective

There’s an almost 3D quality to this image of a portion of the Milky Way, with the illusion that the nebulae are far more distant when in fact they are much closer than the dark dust lanes that meander through the Milky Way.

Head south for a Messier globular duo

The southern constellation of Scorpius hosts two splendid globular clusters, M4 and M80, both of which provide good viewing despite their lowly presentation at mid-northern latitudes.

Set your filtered sights on the Sun

Summer is the season for a spot of solar observing and sunspots, probably the Sun’s most fascinating phenomena, are easier to see than you might think.

A more youthful globular cluster

24 June 2024 Astronomy Now

The Large Magellanic Cloud (LMC), which is the nearest galaxy to our Milky Way at about 159,000 light years, is home to about 60 globular clusters. Pictured here is one of these great balls of stars, namely NGC 2210, which shines in the night sky at magnitude +11.

Follow the leader

This line of galaxies is a cosmic coincidence behind the interacting system Arp-Madore 2105-332, which is a pair of galaxies 200 million light years away in the suitably small constellation of Microscopium.

Cassiopeia A’s many faces

22 June 2024 Astronomy Now

This is the James Webb Space Telescope’s (JWST’s) second view of the Cassiopeia A (Cas A) supernova remnant, the remains of a massive star that exploded in the late 17th century.
